Setting
This parameter sets minimum motor frequency at which motor will run
irrespective of frequency setpoint. The value set here is valid both for
clockwise and for counterclockwise rotation.
Range: 0.00 to 550.00 (default setting: 0.00)
This parameter sets maximum motor frequency at which motor will run
irrespective of the frequency setpoint. The value set here is valid for both
clockwise and counterclockwise rotation.
Range: 0.00 to 550.00 (default setting: 50.00)
Starts inverter onto a spinning motor by rapidly changing the output fre-
quency of the inverter until the actual motor speed has been found. Then,
the motor runs up to setpoint using the normal ramp time.
Settings 1 to 3 search in both directions:
= 0: Flying start disabled
= 1: Flying start always active
= 2: Flying start active after power on, fault, OFF2
= 3: Flying start active after fault, OFF2
Settings 4 to 6 search only in the direction of the setpoint:
= 4: Flying start always active
= 5: Flying start active after power on, fault, OFF2
= 6: Flying start active after fault, OFF2
Range: 0 to 6 (default setting: 1)
P2373 is a percentage of PID setpoint that PID error r2273 must be ex-
ceeded before staging delay starts.
Range: 0.0 to 200.0 (default setting: 20.0)
This parameter defines the time that PID error r2273 must exceed motor
staging hysteresis P2373 before staging occurs.
Range: 0 to 650 (default setting: 30)
This parameter defines the time that PID error r2273 must exceed motor
staging hysteresis P2373 before destaging occurs.
Range: 0 to 650 (default setting: 30)
P2376 as a percentage of PID setpoint. When the PID error r2273 ex-
ceeds this value, a motor is staged / destaged irrespective of the delay
timers.
Range: 0.0 to 200.0 (default setting: 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 prevented after
a motor has been staged or destaged.
Range: 0 to 650 (default setting: 30)
