Configure the Motor Side Inverter
1. Stay at port 10, which is the port for Motor Side Inverter Control.
2. Navigate to parameter 10/11:110 [Mtr Stop Mode A] and enter a value
of 'Ramp' (1).
3. Navigate to parameter 10/11:229 [Regen Power Lim] and enter a value
of -200%.
4. Navigate to parameter 10/11:204 [Mtr OL Hertz] and enter a value that
reflects the cooling capacity of the motor. See parameter 10/11:204 [Mtr
OL Hertz].
5. Navigate to parameter 10/11:220 [Drive OL Mode] and enter a value of
‘Reduce PWM’ (2).
6. Navigate to parameter 10/11:222 [Current Limit 1] and enter a value
equal to 200% of motor nameplate amps.
7. Navigate to parameter 10/11:256 [OutPhaseLossActn] and enter a value
of ‘FltCoastStop’ (3).
8. Navigate to parameter 10/11:116 [Bus Reg Mode A] and enter a value of
0‘Disabled’.
9. Navigate to parameter 10/11:913 [Autotune Trq Lim] and enter a value
of 100%.
Configure the Motor Encoder Feedback
1. Stay at port 10, which is the port for Motor Side Inverter Control.
2. Navigate to parameter 10/11:1000 [Pri Vel Fb Sel]. Select the encoder
feedback on the feedback card in port 5.
If you are following the guidelines at the beginning of this procedure (with
a 20-750-ENC-1 in slot 5), the resulting value is 50004 ‘Port 5: Enc 0 FB’.
Then enter the two-digit port number for feedback option card, and the
four-digit parameter number for the parameter that displays the feedback.
3. Navigate to parameter 10/11:1013 [PReg Fb Sel]. Then enter the same
value that you used for 10/11:1000 [Pri Vel Fb Sel].
4. Navigate to the port that contains the feedback option card. That would
be port 5 when using a 20-750-ENC-1 in slot 5.
5. Configure the parameters on the feedback option card to match the
encoder you are using.
Parameters 5:1 [Encoder Cfg] and 5:2 [Encoder PPR] when using a 20-
750-ENC-1 in slot 5.
6. Confirm the value of parameter 5:3 [Fdbk LossCfg] is 3 ‘FltCoastStop’.
