Parameter Settings
50.59
Zero Speed Holding
Torque
Range: 0.0 – 30.0% Default: 5.0%
This parameter determines the Zero Speed Holding Torque,
when 50.58=01. The holding torque is in % and should be
increased slowly until proper holding torque is achieved. A
value too high will cause increased motor current and
temperature, which could lead to premature motor failure.
Only use this feature with a Vector Duty motor capable of a
1000:1 turn down ratio.

HOA and LOC/REM
Stop Methods

This parameter allows the user to choose the stop method
when the HOA or LOC/REM switch is moved from one
location to another.
50.62
OV Fault During Stop
State
Range: Default: 00
00: Disable
01: Enable
This parameter automatically resets any OV Fault during a
STOP state, that would be caused by a high incoming line and
not motor regeneration. There is no limit to the quantity of
resets. Once the MVX is in a RUN state, any over voltage on
the DC bus will cause an OV fault to occur.
