715 [Torq Limit Type]
This parameter determines the response of the drive during a current limiting
condition.
• “T Lim PosNeg” = The active positive torque limit is set by the value defined in
Par 7 [Current Limit] and the active negative torque limit is set by the value
defined in Par 9 [Current Lim Neg].
• “T Lim MtrGen” = With this option the following three conditions apply:
1. If the motor speed is greater than +1% of Par 162 [Max Feedback Spd], the
active positive torque limit is set by the value defined in Par 8 [Current Lim
Pos] and the active negative torque limit is set by the value defined in Par 9
[Current Lim Neg].
2. If the motor speed is less than –1% of Par 162 [Max Feedback Spd] the
active positive torque limit is set by the value defined in Par 9 [Current Lim
Neg] and the active negative torque limit is set by the value defined in Par 8
[Current Lim Pos].
3. If the motor speed is greater than –1% of Par 162 [Max Feedback Spd] and
less than +1% of Par 162 [Max Feedback Spd] the active positive and
negative torque limits are set by the value defined in Par 8 [Current Lim Pos].
Note: The option names were corrected to those shown above for firmware version

Stop Modes
38 [Fast Stop Time]
The amount of time to decelerate the drive to a complete stop and disable the
drive. The deceleration rate for Fast stop = [Maximum Speed] / [Fast Stop Time].
This feature can be used when [Digital Inx Sel] is set to 30 “Fast Stop” or when
certain alarms are configured for “Fast Stop”. See Pars 354 [Aux Inp Flt Cfg] and 365
[OverTemp Flt Cfg].
