2 Parameters
2.2 List of parameters
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.
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.
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
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).
Value: 0: No motor
1: Induction motor
2: Synchronous motor
10: 1LE1 induction motor
13: 1LG6 induction motor
17: 1LA7 induction motor
19: 1LA9 induction motor
100: 1LE1 induction motor
Dependency: When selecting a motor type from the 1LE1, 1LG6, 1LA7, 1LA9 series, parameters p0335, p0626, p0627, and p0628
of the thermal motor model are pre-assigned as a function of p0307 and p0311.
Caution: If a motor is selected, which is not contained in the motor lists (p0300 < 100), then the motor code number must be
reset (p0301 = 0), if previously a motor was parameterized from the motor list.
Note: Once the Control Unit has been powered up for the first time or if the factory settings have been defined accordingly,
the motor type is pre-configured to induction motor (p0300 = 1).
If a motor type has not been selected (p0300 = 0), then the drive commissioning routine cannot be exited.
