Set the ENABLE parameter in the SLEW RATE LIMIT function block to FALSE.
This disables ramp-hold during deceleration on high link volts feature.
If in Volts/Hz motor control mode, the VOLTAGE MODE parameter in the
VOLTAGE CONTROL function block MUST be set to FIXED. This will ensure the
motor is not overfluxed by the boosted 720V DC Bus. Failure to do this may lead to
motor overheating and possible burn out.
