150 Parameters
19.09 Speed TripMargin Defines, together with 20.01 Maximum speed and 20.02
Minimum speed, the maximum allowed speed of the motor
(overspeed protection). If actual speed (01.01 Motor speed
rpm) exceeds the speed limit defined by parameter 20.01 or
20.02 by more than the value of this parameter, the drive trips
on the OVERSPEED fault.
Example: If the maximum speed is 1420 rpm and speed trip
margin is 300 rpm, the drive trips at 1720 rpm.
0.0 … 10000.0 rpm Overspeed trip margin. 10 = 1 rpm
19.10 Speed window Defines the absolute value for the motor speed window
supervision, i.e. the absolute value for the difference between
the actual speed and the unramped speed reference (01.01
Motor speed rpm - 03.03 SpeedRef unramp). When the motor
speed is within the limits defined by this parameter, signal
02.24 FBA main sw bit 8 (AT_SETPOINT) is 1. If the motor
speed is not within the defined limits, bit 8 is 0.
0 … 30000 rpm Absolute value for motor speed window supervision. 1 = 1 rpm
