Setting
This parameter selects stop mode for external motors when mo-
tor staging is in use.
= 0: Normal stop (factory default)
= 1: Sequence stop
This parameter selects configuration of external motors (M1, M2)
used for motor staging feature.
= 0: Motor staging disabled
= 1: M1 = 1 x MV, M2 = Not fitted
= 2: M1 = 1 x MV, M2 = 1 x MV
= 3: M1 = 1 x MV, M2 = 2 x MV
This parameter enables motor cycling for the motor staging fea-
ture.
= 0: Disabled (factory default)
= 1: Enabled
P2373 as a percentage of PID setpoint that PID error P2273 must
be exceeded before staging delay starts.
Range: 0.0 to 200.0 (factory default: 20.0)
This parameter defines the time that PID error P2273 must ex-
ceed motor staging hysteresis P2373 before staging occurs.
Range: 0 to 650 (factory default: 30)
This parameter defines the time that PID error P2273 must ex-
ceed motor staging hysteresis P2373 before destaging occurs.
Range: 0 to 650 (factory default: 30)
P2376 as a percentage of PID setpoint. When the PID error
P2273 exceeds this value, a motor is staged / destaged irrespec-
tive of the delay timers.
Range: 0.0 to 200.0 (factory default: 25.0)
Note: The value of this parameter must always be larger than
staging hysteresis P2373.
This parameter defines the time for which delay override is pre-
vented after a motor has been staged or destaged.
Range: 0 to 650 (factory default: 30)
This parameter sets the frequency at which the digital output is
switched during a (de) staging event, as the inverter ramps from
maximum to minimum frequency (or vice versa).
Range: 0.0 to 120.0 (factory default: 50.0)
This parameter displays output word from the motor staging fea-
ture that allows external connections to be made.
Bit 00: Start motor 1 (yes for 1, no for 0)
Bit 01: Start motor 2 (yes for 1, no for 0)
This parameter displays hours run for external motors.
Index:
[0]: Motor 1 hrs run
[1]: Motor 2 hrs run
[2]: Not used
Range: 0.0 to 4294967295 (factory default: 0.0)
