Description
Torque Limit
Sets the torque limit value as a percentage of the motor rated
torque. Four individual quadrants can be set.

Hardware Protection
Selects the DB protection only when using 3% duty cycle heatsink
mount Yaskawa braking resistor. This parameter does not enable or
disable the DB function of the Drive.
0: Not Provided
1: Provided
When the cooling fin temperature exceeds the value set in this
parameter, an overheat alarm (OH) will occur.
Selects the Drive operation upon an OH pre-alarm detection.
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
Selects the detection of input current phase loss, power supply volt-
age imbalance, or main circuit electrostatic capacitor deterioration.
0: Disabled
1: Enabled
Selects the detection of output current open-phase.
When applied motor capacity is too small for Drive capacity,
output phase loss may be detected inadvertently. In this case, set to 0.
0: Disabled
1: 1-phase Loss Detection
2: 2/3-phase Loss Detection
Enables and disables the Drive's output ground fault detection.
0: Disabled
1: Enabled
Controls the heatsink cooling fan operation.
0: Fan On-Run Mode - Fan will operate only when the Drive is
running and for L8-11 seconds after RUN is removed.
1: Fan Always On - Cooling fan operates whenever the Drive is
powered up.)
This parameter sets the delay time for the cooling fan turn off after
the run command is removed when L8-10 = 0.
When the Drive is installed in an ambient temperature exceeding
its rating, the Drive overload (OL2) protection level is adjusted.
