[AF130] = 03: Brake control 2, the following parameters are valid.
Brake release delay time
Brake apply delay time
Brake check time
Servo lock time at start
Servo lock time at stop
Precautions for Correct Use
• Since the brake control 2 generates the servo lock status when the brake is on, use 09: zero
speed range sensorless vector control or 10: vector control with sensor for the [AA121] con-
trol method.
• Selecting the control methods other than the above will replace the operation part of the
servo lock with the DC braking operation. Servo lock time is applied at start/stop operation
even when this is a DC injection braking.

The inverter starts the output and performs the servo lock for the servo lock time at start.
(If the [AA121] control method is neither 09: zero speed range sensorless vector control nor 10: vector
control with sensor, the DC braking is applied.) (1)
After the brake release delay time passes, the brake release signal 037[BRK] is turned on. (2)
The operation varies depending on whether the brake check signal 037[BOK] is set to the input terminal
function.
After the servo lock time at start passes, there is an acceleration. (3)

If the 037[BOK] is not turned on during the brake check time, the inverter trips with the
[E036] brake error outputting the fault signal 038[BER].
After the release signal 037[BRK] signal is turned on, there is a waiting for the servo
lock time at start to pass.
