Description: Sets the fan run-on time after the pulses for the power unit have been canceled.
Note: - Under certain circumstances, the fan can continue to run for longer than was set (e.g. as a result of the excessively
high heat sink temperature).
- For values less than 1 s, a 1 s run on time for the fan is active.
- for a PM230 power unit, sizes D - F the parameter is ineffective.
Description: Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage condition.
Dependency: Refer to: F30003
Description: Threshold to detect a DC link overvoltage.
If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to DC link overvoltage.
Dependency: Refer to: F30002
Description: Selecting the motor type.
The first digit of the parameter value always defines the general motor type and corresponds to the third-party motor
belonging to a motor list:
1 = induction motor
2 = synchronous motor
xx = motor without code number
xxx = motor with code number
The type information must be entered to filter motor-specific parameters and to optimize the operating characteristics
and behavior. For example, for synchronous motors, power factor (p0308) is neither used nor displayed (in the
BOP/IOP).
The following applies for values < 100:
Motor data must be manually entered.
The following applies for values >= 100:
Motor data are automatically loaded from an internal list.
