pendent to handle standard induction motors whose cooling is limited by the shaft-
mounted fan. Blower-cooled motors and most inverter-duty motors do not have this lim-
itation.
This parameter operates as a percentage of the longest ramp time. This time then de-
fines the amount of time a deceleration to stop can take without causing a “Regen Time-
out” fault. For example, if “Decel Time 1” is 5.0 seconds, “Decel Time 2” is 10.0 seconds,
and “Max Regen Ramp” is 300%, a deceleration to stop that takes more than 30 seconds
will cause a “Regen Timeout” fault in the drive.
Both of these parameters can be used to resolve stability problems if they occur. Use Pa-
rameter 615 if the load has significant inertia with respect to the motor itself.
This parameter configures the analog signal that will be applied to the Vmet output pin.
The following data values may be assigned to this parameter:
