Question
Can I use a SureServo drive with the P3-HSO module?
Answer
Yes. There is an HSO-to-SureServo wiring diagram in the P3-HSO insert.- By default, the SureServo is programmed for Pt mode (think "Pulse Train").
- Follow the Quick Start Guide in Appendix A of the SureServo manual. When you have finished the initial section "Spin the Motor", go to the "Position Mode" section.
- Follow the procedures in the "Pt Mode" sub-section.
You will need to set P2.15 and 2.16 to "0" at the end of this section, as Overtravels will need to be wired into the GP inputs of the HSO module. If you don't do this, you will get an ALE 14/15 alarm on the SureServo.
- Go to the P3 software, and select "Hardware Config". Either add or edit your HSO module, and assign your Overtravels and/or Home Sensor (if any are used), into the GP Input section of the Module Setup (use Status Tag names like "Ch1_Rev_Overtravel" or "Ch1HomeSensor", much easier to recognize in ladder later on)
- In the "Channel x Setup" tab, assign your tags as your application requires. Overtravels will be configured in the "Physical Limits" section, and the meaningful tag names make it easy to select your inputs. By default, the HSO is setup to deliver Pulse/Direction output signals, and that is what the SureServo is configured for as well.
- After the channels are configured as desired, click OK, exit the Hardare Config, and Compile and Save your project.
- Now, move to creating the ladder in the P3 software. Typically, the HOME, VMOV and SMOV would be the most used instructions. HOME instruction would usually be used in a linear application, with finite travel ( like a linear slide, or milling machine table). A rotary application like nip or feed rollers typically would not use a Home sensor.
- SMOV- This is a simple trapezoidal profile, can be used in Absolute mode ( like the previously mentioned linear slide) or in Relative mode ( like a feed to length, or nip roller application). The "Target" entry is your actual position in Absolute mode ( like moving to different numbers on a ruler - input a different number, the instruction delivers pulses in the proper direction to get to that number). In Relative mode, this would be the length of your feed.
- VMOV -Typically, this instruction will be used as your "JOG" feature (see FAQ 7 in this section).
