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.
0 : Disregard Existing RUN Command
1 : Accept Existing RUN Command

DC Injection/Zero
SpeedThreshold
Sets the frequency to start DC Injection Braking or Short Circuit Braking near the end of a stop ramp.
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp to Stop].
Determined by A1-02
(0.0 - 10.0 Hz)

Short Circuit Brake Time @
Stop
Sets the Short Circuit Braking time at stop. A1-02 = 8: 0.00 s
Other than A1-02 = 8: 0.50 s
(0.00 - 25.50 s)
b2-18
(0177)
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)]
