Operation
To reverse the direction of rotation, switch the wires of two phases of U, V, and W as
shown below.

5-2-4 Motor Deceleration is Too Slow
H Deceleration Time is Too Long Even if a Braking Resistor is
Connected.
•Value 0 (stall prevention during deceleration) is set in n33.
When a braking resistor is connected, always set "1" (no stall prevention during decel-
eration) in n33. If "0" is set, the braking resistor will not be used.
•The deceleration time set in n21 is too long.
Check the deceleration time setting.
•Motor torque is insufficient.
If the constant settings are normal and overvoltage does not occur, motor capacity is
insufficient.
Motor capacity should be increased.
5-2-5 Vertical-axis Load Drops when Brakes are
Applied
•Sequence is incorrect.
The Inverter remains in DC braking status (50% of the n31 setting) for 0.5 second after
deceleration is complete. Modify the sequence so that brakes are applied when the
Inverter enters DC braking status.
•Brakes are inappropriate.
Always use control brakes, not holding brakes.
