Limitation:
Too short of an Accel time can result in Torque limit warning (W12) and/or DC over voltage warning (W7). Ramping is stopped when the frequency converter has
reached Torque limit motor mode (par. 4-16).
Too short of a Decel time can result in Torque limit warning (W12) and/or DC over voltage warning (W7). Ramping is stopped when the frequency converter reaches
the Torque limit generator mode (par. 4-17) and/or the internal DC over voltage limit.

Function:
Constant acceleration/deceleration.
Smooth jerk compensated acceleration/deceleration.
Function:
Enter accel time from 0 Hz to rated motor frequency (f
Choose a accel time ensuring that torque limit is not exceeded, see par. 4-16.
Function:
Enter decel time from rated motor frequency (f
Choose a decel time that does not cause over-voltage in due to regenerative operation of motor. Furthermore, regen-
erative torque must not exceed limit set in par. 4-17.
