Deceleration mode
H06 specifies the deceleration mode to be applied when a run command is turned OFF.
Data for H06
Function
0
Normal deceleration
The inverter decelerates and stops the motor according to deceleration commands specified by
H04 (Acceleration/deceleration pattern), F08 (Deceleration time 1), and E09 (Deceleration time
2).
1
Coast-to-stop
The inverter immediately shuts down its output, so the motor stops according to the inertia of the
motor and machine and their kinetic energy losses.
➢
When reducing the reference frequency, the inverter decelerates the motor according to the
deceleration commands even if H06 = 1 (Coast-to-stop).
Setting the H13 data to "1" (ON) enables forced brake control. If regenerative energy produced during
deceleration of the motor and returned to the inverter exceeds the inverter’s braking capability, an
overvoltage trip will occur. The forced brake control increases the motor energy loss during deceleration,
increasing the deceleration torque.
