Solar Drive Autotuning
For a EM12 SP Drive or EM15 SP Drive with Single Line keypad, please set the following parameters:
- Set F1-01 up to F1.05 according to motor nameplate
- Set F1-37 = 1 for static auto tuning (if F0-02=1, first set it to 0, for autotuning)
Press RUN to start the autotuning process. The Solar Drive and Motor will go through a short working process and stop by itself, after which certain motor parameters would have been optimised.
For a EM15 SP Drive with Double Line keypad, please set the following parameters:
- Set d0-00 up to d0-04 according to motor nameplate
- If the motor can be disconnected from the load:
- Set d0-30 = 2 and press ENTER
- If the motor cannot be disconnected from the load:
- Set d0-30 = 3 and press ENTER
*if b0-02=1, first set it to 0, for autotuning)
Press RUN to start the autotuning process. The Solar Drive and Motor will go through a short working process and stop by itself, after which the d0-05 up to d0-09 parameters would have been optimised.
- d0-05: Stator resistance (asynchronous motor)
- d0-06: Rotor resistance (asynchronous motor)
- d0-07: Leakage inductive reactance(asynchronous motor)
- d0-08: Mutual inductive reactance(asynchronous motor)
- d0-09: No-load current(asynchronous motor)
PLEASE NOTE: Autotuning cannot be done when the drive is in Terminal Control or Remote Control Mode (needs to be in keypad Control mode: b0-02=0 or F0-02=0). After setting the Autotune Parameter the keypad will display “TUNE”, when this is displayed press the RUN button and let the drive complete the autotuning process (~30 seconds) after which the drive can be used.
*When using a single Solar Drive to run more than one motor, do not perform autotuning.
