P2378 Staging frequency f, %fMax
The frequency as a percentage of max. frequency. During a (de) staging event, as the variable
speed drive ramps from maximum to minimum frequency (or vice versa) this is the frequency
at which the relay (DOUT) is switched. This is illustrated by the following diagrams.
Unit: % Min: 0.0 Def: 50.0 Max: 120.0
Level 3
Details:
The frequency as a percentage of fMax at which an external motor will be started or stopped
r2379 CO/BO: Status of motor staging
Output word from the motor staging feature that allows external connections to be made.
Unit: - Min: - Def: - Max: -
Level 3
Bit fields:
Bit00 Start motor 1 0 YES, 1 NO
Bit01 Start motor 2 0 YES, 1 NO
P2380[3] Motor hours run
Displays hours run for external motors. To reset the running hours, set the value to zero, any
other value is ignored.
Unit: h Min: 0 Def: 0 Max: 100000
Level 3
Index:
P2380[0] : Motor 1 hrs run P2380[1] : Motor 2 hrs run P2380[2] : not used
Note:
To reset the running hours, set the value to zero, any other value is ignored.
P2390 Hibernation frequency
When the variable speed drive under PID control drops below hibernation setpoint, the
hibernation timer P2391 is started. When the hibernation timer has expired, the variable speed
drive is ramped down to stop and enters hibernation mode (see diagram below).
Unit: % Min: 0 Def: 0 Max: 200.00
Level 3
Details:
Hibernation frequency setpoint (frequency the motor output will turn off).
P2391 Hibernation timer
When the hibernation timer P2391 has expired, the variable speed drive is ramped down to
stop and enters hibernation mode (see description and diagram of P2390).
Unit: s Min: 0 Def: 0 Max: 254
Level 3
Details:
Hibernation restart frequency (frequency the motor output will turn on).
P2392 Restart PID controller deviation [%]
While in hibernation mode, the PID controller continues to generate the error P2294 - once this
reaches the restart point P2392, the variable speed drive immediately ramps to the setpoint
calculated by the PID controller (see description and diagram of P2390).
Once the variable speed drive has left hibernation mode, it is not possible to go back into
hibernation mode, until the variable speed drive output setpoint has reached the restart
setpoint.
Unit: % Min: -200.00 Def: 0 Max: 200.00
Level 3
Details:
Hibernation restart frequency (frequency the motor output will turn on).
P3900 End of quick commissioning
Performs calculations necessary for optimized motor operation.
After completion of calculation, P3900 and P0010 (parameter groups for commissioning) are
automatically reset to their original value 0.
Unit: - Min: 0 Def: 0 Max: 3
Level 1
Details:
Performs calculations necessary for optimized motor operation.
After completion of calculation, P3900 and P0010 (parameter groups for commissioning) are automatically reset to their
original value 0.
Settings:
0=No quick commissioning
1=Start quick commissioning with factory reset
2=Start quick commissioning
3=Start quick commissioning only for motor data
Dependency:
Changeable only when P0010=1 (quick commissioning)
Note:
When setting 1 is selected, only the parameter settings carried out via the commissioning menu "Quick commissioning",
are retained; all other parameter changes, including the I/O settings, are lost. Motor calculations are also performed.
When setting 2 is selected, only those parameters, which depend on the parameters in the commissioning menu "Quick
commissioning" (P0010=1) are calculated. The I/O settings are also reset to default and the motor calculations
performed.
When setting 3 is selected, only the motor and controller calculations are performed. Exiting quick commissioning with
this setting saves time (for example, if only motor rating plate data have been changed).
Calculates a variety of motor parameters, overwriting previous values. These include P0344 (Level 3, motor weight),
P0350 (Level 3, demagnetization time), P2000 (reference frequency), P2002 (Level 3, reference current).
