P2375 Motor destaging delay
Time that PID error r2273 must exceed motor staging hysteresis P2373 before destaging
occurs.
Unit: s Min: 0
P2376 Delay override
Value as a percentage of the PID setpoint. When the PID error r2273 exceeds this value, a
motor is staged / destaged irrespective of the switch-on/off delay timers P2374 and P2375.
Unit: % Min: 0.0
P2377 Delay override lockout timer
Time for which delay override is prevented after a motor has been staged or destaged.
This prevents a second staging event immediately after a first being caused by the transient
conditions after the first staging event.
Unit: s Min: 0
P2378 Staging frequency f, %fMax
The frequency as a percentage of the max. frequency fMax.. During a (de)staging event, as
the VSD ramps from maximum to minimum frequency (or vice versa), this is the frequency at
which the relay (DOUT) is switched. Used to start or stop the external motor.
Unit: % Min: 0.0
r2379 CO/BO: Status of motor staging
Output word from the motor staging feature that allows external connections to be made.
Unit: - Min: -
Bit fields:
Bit00 Start motor 1
Bit01 Start motor 2
Bit02 Start motor 3
P2380[3] Motor hours run
Displays hours run for external motors.
Unit: h Min: 0
Index: P2380[0]: Motor 1 hrs run
Note: To reset the running hours, set the value to zero. Any other value will be ignored .
P2390 Hibernation frequency setpoint
When the VSD under PID control drops below the hibernation frequency setpoint, the
hibernation timer P2391 is started. When the hibernation timer has expired, the VSD is ramped
down to stop and enters the hibernation mode.
Unit: % Min: 0
Note: If the hibernation frequency setpoint = 0, then hibernation is disabled.
P2391 Hibernation timer
When the hibernation timer P2391 has expired, the VSD is ramped down to stop and enters
the hibernation mode (see description of P2390).
Unit: s Min: 0
P2392 Restart PID controller deviation [%]
While in hibernation mode, the PID controller continues to generate an error signal (r2294).
Once this reaches the restart point P2392, the VSD immediately ramps to the setpoint
calculated by the PID controller (see description of P2390).
Unit: % Min: -200.00
Details: Once the VSD has left the hibernation mode, it is not possible to go back into hibernation mode until the VSD output
setpoint has reached the restart setpoint.
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
Details: 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 the parameters that 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 4, motor weight),
P0347 (level 4, demagnetization time), P2000 (reference frequency), P2002 (reference current).
