4. ASCL Control Startup Steps

Asynchronous Sensorless Closed Loop (ASCL) uses a control alogrithm to automatically measure and
model the motor characteristics without encoder feedback. ASCL offers excellent control in both stable
and dynamic motor operation, accurate speed control, and high speed stability without the additional
cost and complexity of an encoder. Follow the steps below for ASCL motor control startup.
1. Set CP02 = 0 for ASCL.
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 ACTUAL 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. Motor Ready to Operate (See Section 8 for Drive faults and Section 9 for Operational Problems).
8. Adjust as necessary.
- Speeds, CP13 - 15.
- Accel/Decel Times CP16 - 17.
- Speed Control Gains.
- CP22 = Proportional.
- CP23 = Integral.
- CP24 = Integral Offset.

= 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.**
