MG.02.C2.02 - VLT
Function:
Constant acceleration/deceleration.
Smooth jerk compensated acceleration/deceleration.
Function:
Enter ramp-up time from 0 Hz to rated motor frequency (f
set in par. 1-23.
Choose a ramp-up time ensuring that torque limit is not excee-
ded, see par. 4-16.
Function:
Enter ramp down time from rated motor frequency (f
1-23 to 0 Hz.
Choose a ramp down time that does not cause over-voltage in
inverter due to regenerative operation of motor. Furthermore,
regenerative torque must not exceed limit set in par. 4-17.
Function:
Constant acceleration/deceleration.
Smooth jerk compensated acceleration/deceleration.
Function:
Enter ramp-up time from 0 Hz to rated motor frequency (f
set in par. 1-23.
Choose a ramp-up time ensuring that output current does not
exceed current limit set in par. 4-18 during ramping.
Function:
Enter ramp down time from rated motor frequency (f
1-23 to 0 Hz.
