Setting parameters
Parameter Function Setting
P2370[0...2] Motor staging stop mode This parameter selects stop mode for external motors when
motor staging is in use.
= 0: Normal stop (factory default)
= 1: Sequence stop
P2371[0...2] Motor staging configuration 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
P2372[0...2] Motor staging cycling This parameter enables motor cycling for the motor staging
feature.
= 0: Disabled (factory default)
= 1: Enabled
P2373[0...2] Motor staging hysteresis [%] P2373 as a percentage of PID setpoint that PID error P2273
must be exceeded before staging delay starts.
Range: 0.0 ... 200.0 (factory default: 20.0)
P2374[0...2] Motor staging delay [s] This parameter defines the time that PID error P2273 must
exceed motor staging hysteresis P2373 before staging
occurs.
Range: 0 ... 650 (factory default: 30)
P2375[0...2] Motor destaging delay [s] This parameter defines the time that PID error P2273 must
exceed motor staging hysteresis P2373 before destaging
occurs.
Range: 0 ... 650 (factory default: 30)
P2376[0...2] Motor staging delay override [%] P2376 as a percentage of PID setpoint. When the PID error
P2273 exceeds this value, a motor is staged / destaged
irrespective of the delay timers.
Range: 0.0 ... 200.0 (factory default: 25.0)
Note: The value of this parameter must always be larger than
staging hysteresis P2373.
P2377[0...2] Motor staging lockout timer [s] This parameter defines the time for which delay override is
prevented after a motor has been staged or destaged.
Range: 0 ... 650 (factory default: 30)
P2378[0...2] Motor staging frequency f_st [%] This parameter sets the frequency at which the digital output
(DO) is switched during a (de) staging event, as the inverter
ramps from maximum to minimum frequency (or vice versa).
Range: 0.0 ... 120.0 (factory default: 50.0)
r2379.0...1 CO / BO: Motor staging status word This parameter displays output word from the motor staging
feature 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)
P2380[0...2] Motor staging hours run [h] 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 ... 4294967295 (factory default: 0.0)
