♦ Transvektor control (set B60.X / P432 in FP-WRS to 2)
♦ The motor is de-coupled
♦ The drive converter is powered-down
The following connectors are included in the FP-TRV. The sequence must be
maintained.
1. In order to optimize the pre-control, de-activate the quadrature arm with
ISQ.ENQ / P815 = 0
2. Set ISR.NA2 / P809 to 2.2
3. Set ISR.NA1 / P808 to 2.08
The current controller is then fully activated in the ϕ1 axis.
4. Power-up the drive converter and, for example, run-up to 25 Hz
5. Compare the flux setpoint IMV.PSS with the flux actual values of the voltage
model UMOD.PUM and the current model IMOA.PIM. The following
relationships should be fulfilled:
UMOD.PUM ≥ IMU.PSS, approx. + 2 - 3 %
IMOA.PIM ≤ IMU.PSS, approx. − 2 - 3 %
Example: IMU.PSS = 94 %, UMOD.PUM = 97 %, IMOA.PIM = 91 %
The values should be checked at various frequency setpoints. They should be
approximately constant up to the motor rated frequency.
6. Check the motor voltage actual values KPW1.YB at half the rated frequency
and at the rated motor frequency. Approximately 47 % or 95 % respectively,
should be displayed.
