Description
Defines the third frequency point of the custom U/f curve.
Defines the fourth frequency point of the custom U/f curve.
Programmable protection functions
Selects how the drive reacts when the drive trips to fault
excepting Hardware critical faults (OVERCURRENT, DC
OVERVOLT and SHORT CIRC), SAFE TORQUE OFF,
STO1 LOST and STO2 LOST faults.
Drive makes coast stop when drive trips fault.
Drive makes emergency ramp stop when drive trips fault
using the emergency ramp stop deceleration time (par.
22.08).
Process PID (PID1) control parameter set 1.
Defines the start limit for the sleep function. If the motor
speed is below a set level (4023) longer than the sleep
delay (4024), the drive shifts to the sleeping mode: The
motor is stopped and the control panel shows alarm
message PID SLEEP (2018).
Parameter 4022 SLEEP SELECTION must be set to
INTERNAL.
