Hello everyone,
I have an emerson Commander SK, 2.2 KW, 220 single phase drive that I'm having a problem with. So the drive was working fine and while troubleshooting and entirely different issue I changed parameter #05 from Pr to PAd and #11 from 0 to 1 so I can run the motor using the key pad on the drive. After done I set the parameters the way they were. The drive went into ih (inhibited) and couldn't get it to ready state. Knowing that "When the setting of Pr 05 is changed, the appropriate drive configuration parameters are set back to their factory default", I went through every parameter (form 0 to 80) and matched another drive that is wired and works exactly the same but the drive is till in "ih" mode. Then after calling the equipment tech support and not having much luck with them either I put another drive into PAd mode to move products out and that drive also is now in "ih" even though I put the parameters back the way they were. I can get the drive to work by changing parameter #11 but and then jumper certain terminals which means that the terminals configuration has been changed and there parameters that I'm not setting correctly but which are they?
I'm going through the advanced user guide as I write this thought I'd ask for help as well.
The attached picture shows the wiring of the drive. They're basically wire as follows:
B3: output to alarm input.
B5: Forward
B6: Reverse
T4&B7: Speed presets
T2: Is marked on the wiring schematic as RST- which I haven't figured out what it is yet.
Are all the parameters accessible from the keypad?
Thanks a lot
