Factory Setting
The value of this parameter sets the DC Hold Voltage that is applied to the
motor during the DC Hold Time set by Parameter 12.
The optimum setting for this parameter is a function of external variables
— motor size, load inertia, friction load and other factors. It is
recommended that this setting be the lowest value needed to achieve the
required holding or braking action at zero speed. Voltages above rated
motor nameplate value can produce high motor currents during the hold or
brake cycle which may lead to motor overheating.
!
ATTENTION: A power interruption lasting longer than 500mS or
a malfunction in the solid-state circuitry will cause a loss of
holding or braking torque. If a hazard of injury due to movement of
equipment or material exists, an auxiliary mechanical braking
device must be used.
