Will the DOP professional software work with the GS series of drives?
No, The DOP software is used exclusively to program Hitachi drives. The GS series have there own software called "GSoft" which is Now available under GS Drives.

How can I establish a minimum speed on the GS2?
Adjust P-6.16 lower bound of output frequency.
FAQ ID: 945
Can the GS1 drive perform dynamic braking?
No, it does not have this function. Also, since the dc bus is isolated internally, a dynamic braking unit would not be feasible either.
FAQ ID: 946
Can you control the GS drives with TND or Entivity studio?
FAQ ID: 947
Can I use the MOP type terminal speed control with acceleration and deceleration times of less than 1 second? E.G. settings 14 and 15 for DI3-DI6 on GS2 and 14 and 15 for DI3 and DI4 on the GS1.
When the acceleration time or decelration time is set below 1 second, there is not enough time for the cpu to process the speed change.
If the lower times are required, use any of the other methods of speed control available.

Can I power the GS3 series drives from the D.C. Bus?
No the GS3 has input phase detection that will not let the drive run without three phase input.
FAQ ID: 1029
My horsepower requirements fit either the GS2 or the Durapulse drive families,which is the best choice for me?
Both drives will run most applications, but if you need more speed control or low speed performance the Durapulse would be the drive to use .The primary difference in the drives is the control method. The GS2 is a Volts/Hertz drive and the GS3/Durapulse is a Sensorless vector drive. An example of the different applications is if you needed to run a conveyor both drives will work fine. If you need to operate a spindle that needs to maintain a stable speed across its range you would need the Durapulse with a feedback card.

Can I use these on electric vehicles?
AutomationDirect is a direct seller of automation and industrial control products such as PLCs, sensors, pushbuttons, AC drives/motors, enclosures, operator interfaces, and much more.
AutomationDirect is aware that many engineers and hobbyists are currently designing or converting vehicles from internal combustion engines to electric engines. Our current drive and motor products are intended to be used in industrial applications. As a result, AutomationDirect does not currently support or encourage the use of our products in electric vehicles. We apologize for this, and may revise this policy at a later date if more suitable equipment becomes available.

Is there a good way to do a master/follower with the VFDs?
Master/follower is a combination of AC drives and motors to get the follower motor to have a proportional speed of the master motor.
The GS2 and GS3 VFD's have an analog output 0-10 Volt for frequency.
This can be used for outputting an approximate speed control signal.
Error can be from 1% to 5 %, depending on the speed percentage; at lower speeds, the error is bigger.
You may offset the input frequency of the follower using the parameters P4-01 to 4-03
Just connect AO of the master into the analog input for frequency set point on the follower with a wire. Connect the ACM terminals from the master to the follower.
Program the analog output for frequency and the analog input for 0 10 Volt (P4-00 as 2)
If you want higher precision, consider the use of Durapulse drives with encoder feedback.
This will reduce the error to less than 0.5%.
In either case, this is not electronic gearing.

Do you have a cable to connect my GS2 drive to my DirectLogic or Click PLC?
For one GS2 drive ONLY, you can use the GS-RJ12-CBL-2 to connect to the 2nd port of a DL05 or Click PLC. The slider switches on the GS2 need to be in the RS232 positions.
For 2or more Drives, from one 06 or 260 you can use
GS-485HD15-CBL-2 to any port on the ZL-CDM-RJ12X4 or ZL-CDM-RJ12x10, then plug GS-485RJ12-CBL-2 cables into the drives and any remaining port on the CDM module. The slider switches need to be in the RS485 positions.

How can I set a higher maximum speed (RPM/frequency) than 60hz for the drive and motor ?
Change the setting in P0.04 (Motor Maximum RPM)
Do not exceed the motor manufacturer's maximum RPM specification
FAQ ID: 1245
Does the GS1 have Line Start Lockout feature like the GS3 ?
FAQ ID: 1265
Can the sinking type 4 - 20mA analog output of the Click PLC be used to provide a speed reference signal for the GS series drives?
The GS2 and Durapulse drives are compatible with the 4 - 20mA sinking analog output of the Click PLC. The GS1 drive is not compatible as the discrete and analog inputs share the same common connection. Wiring should be as follows:

I get a duplicate function error when setting external source of speed.
Set 4.13 = 4
FAQ ID: 1376
Can I feed a GS3 drive with single-phase 230volt input and power a 3-phase motor? Can I use a single high-leg 230 volt supply (one power leg at 230v and a neutral), which is common in Europe?
Yes, but only up to the 3HP rating.
No derating is required.
For a single high leg supply, the 3 hp maximum still applies, and you connect the high leg and the neutral to any of the L supply terminals.
Note that only GS1-2xxx, GS2-2xxx or GS3-2xxx are suitable for this, as they are 230volt drives.
FAQ ID: 1520
Can I use a drive on a mill or lathe?
While possible, the main limitation is a VERY important one- you will lose power if you slow the motor down with a drive.
This means you can't take heavy cuts, or use large cutting tools, which are the primary reasons for reducing speed.
If you are reducing speed for hand operations like sanding, then there should be no issues. The same holds true for light cuts, the power loss due to the reduced motor speed may not affect the operation. But...you must be aware that it could.
FAQ ID: 1552
My GS3 won't auto-start after a power outage ( or after a shift to generator power). What can I do to correct this?
Momentary Power Loss
The GS3 drives have a maximum setting of 5.0 seconds for P6.02 ( Momentary Power Loss), but larger GS3 drives ( about 5 hp and up), can actually take longer to fully power down.
So if the power is off for 6-12 seconds, the drive becomes stuck in a gray area, and won't go back into RUN.
What is ideal is to have a main supply contactor upstream of the drive, that is controlled by a Time Delay Relay, in On-Delay mode.
Once the power comes back on, the TDR begins timing, and after 15 seconds, it closes the Normally Open contact pair it energizes the contactor, which supplies power to the drive. The drive had sufficient time to fully power down, and will power up normally.
As an alternative, use the TDR to make sure the RUN signal doesn't come on to the drive till after that 15 second period. The TDR breaks the signal from DCM ( or +24, depending on drive setup) and Digital Input 1. So the TDR is powered up, as before, and after 15 seconds, it closes its' contacts and makes the circuit into Digital Input 1, for the RUN command.
MS4SM-AP-ADC is an example TDR
TP411X base for TDR
