0.0: disable (when brake resistor used)
During deceleration, the DC bus voltage may exceed its Maximum Allowable Value due to
motor regeneration. When this function is enabled, the AC motor drive will not decelerate
further and keep the output frequency constant until the voltage drops below the preset value
again.
