Precautions for Correct Use
• Do not use the brake control 1 function when position/torque controls are performed.
• Do not use the brake control 1 function when the synchronous motor (permanent magnet
motor) is used.

Brake check signal

Once the inverter receives an operation command, it starts the output and accelerate to the release fre-
quency. (1)
When the brake release establishment waiting time passes after the release frequency is reached, the
inverter outputs the brake release signal 037[BRK]. (2)
Precautions for Correct Use
At this time, if the output current is less than the current set for the release current, the brake
release signal is not output and the trip occurs with the [E036] brake error outputting the brake
fault signal 038[BER].
The operation varies depending on whether the brake check signal 037[BOK] is set to the input terminal
function. (3)
With [BOK] setting
Without [BOK] setting
If the brake check signal [BOK] is not selected, when the brake release signal is output, the inverter
starts accelerating again to the set frequency after the acceleration waiting time passes. (4)

Brake check waiting time
[AF134]
The inverter turns on the release signal [BRK] and waits for the input (ON) for the
check signal [BOK] without accelerating during the brake check waiting time. If the
[BOK] is not turned on during the above time, the inverter trips with the [E036] brake
error outputting the fault signal [BER].
After the release signal [BRK] is turned on, the process goes to the item 4 regardless
of the brake check waiting time.
