Description
Settings for Speed matching. See section
protection) on page 87.
Note: When Shaft synchronisation is active, avoid using this function as the
speed correction from synchronisation block can do step speed corrections
after the speed ramp.
Selects whether Speed matching is active or not.
Note: This function should be activated only for drives running in Speed mode.
Active.
Inactive.
Defines the motor speed deviation level in percentage of maximum speed (Par.
20.02) when the drive is running at the set point. Value is applicable in both
forward and reverse direction. A speed above this level when the drive is at set
point, means that the speed error is too high. See also parameter 75.03.
Percent.
Defines the Speed match fault delay time when the speed error is higher than
defined in the parameter 75.02
FLT if the speed error is higher than the SP DEV LEV for more than the delay
time defined.
Time. Defines the Speed match fault delay time.
Defines the Speed matching deviation when the drive is accelerating or
decelerating. While accelerating/decelerating, if the absolute difference
between the rate of ramped speed reference, and the rate of change of actual
speed, is greater the defined value and continues for a period defined in the
Par. 75.03 then the drive will trip on SPD MATCH FLT during acceleration/
deceleration. The rate of change of ramped speed reference is calculated
using the active acceleration/deceleration time. See section
(internal overload protection)
Percent per second
Settings for Torque proving. See section
on page 88.
Selects whether Torque proving is active or not.
Active.
Inactive.
Defines the Torque proving fault delay time. The drive trips on TORQ PROVE
FLT if actual motor torque of 30% has not been attained in the time interval
defined.
Time. Defines the Torque proving fault delay time.
