6. Closed Loop Control Startup Steps

Closed Loop Control uses an encoder to provide feedback for precise motor control. Speed
measurements are fed back to the drive real time and constantly compared against commanded values to
be adjusted accordingly. Follow the steps below for Closed Loop motor control startup.
1. Set CP02 = 2 for Closed Loop Control.
2. Enter the basic motor information from the motor nameplate.
- CP03 = Rated Power (kW), P
- CP04 = Rated Speed (rpm).
- CP05 = Rated Current (A).
3. Load the motor data.
- Set CP09 = 2 ' A ct.DC Voltage (F5-M/S)' .
- Will display 'DONE!' and go back to 0 'done' when load complete.
4. Perform the motor learn.
- Note! The drive will output current at zero speed, but may not generate enough torque to
hold the load during the measurement. Set CP15 Inspection Speed to zero and prevent motor
brake from picking during process (eg. Remove brake wire from controller).
- Set CP10 = 7 'auto ident without move +1000 Hz' .
- Navigate to CP01 Inverter Status. Press and hold Inspection Run Command.
- When CP01 = 127 'Calculate Drive Data Ready' . Release Inspection Run Command.
- Set CP10 = 0.
5. Set CP11 Electronic Motor Overload Protection.
- For single motors, set the CP11 = 0 'Error, No Auto Retry' .
- Set CP12 Electronic Motor Overload Protection Current = Motor Rated Current.
- For parallel motors, set CP11 = 6 'Warning by Digital Output' .
- CP12 is not used when CP11 = 6 'Warning by Digital Output' .
6. Set Speeds and Accel/Decel Times (See Section 7 for accel/decel time calculation)
- CP13 = High Speed (rpm).
- CP14 = Low Speed (rpm.)
- CP15 = Inspection Speed (rpm).
**CP16 or 17 = 1000(Desired Accel or Decel Time - 5 sec.) / Command RPM
7. Enter the encoder pulses per revolution (ppr) in CP20.
8. Motor Ready to Operate (See Section 8 for Drive faults and Section 9 for Operational Problems).
8
= P x 0.746.
(kW) (hp)
- CP06 = Rated Frequency (Hz).
- CP07 = Rated Voltage (V).
- CP08 = Rated cos (phi) [Power Factor].*
*Use 0.90 if unknown.
- CP16 = Acceleration Time.**
- CP17 = Deceleration Time.**
