Run Command at Power
Up
Sets drive response when the CPU changes from de-energized to energized and there is
an active Run command. Set this parameter in applications where energizing or de-
energizing the drive enables the Run command. When the CPU stays energized during
loss of power, L2-01 [Power Loss Ride Through Select] sets operation.

CLV Start Selection
Sets the conditions for the drive to accept a Run command when A1-02 = 3, 7 [Control
Method Selection = CLV, CLV/PM]. Usually it is not necessary to change this setting.

DC Injection/Zero
SpeedThreshold
Sets the frequency to start DC Injection Braking, Short Circuit Braking, or Zero Servo
near the end of a stop ramp.
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp to
Stop].

Short Circuit Braking
Current
Sets the Short Circuit Braking Current as a percentage of the motor rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
