S3.11
Setting velocity via Up/Down Factory Default 1.00 Hz / s
Setting range 0.10 − 100.00 Hz / s Minimum unit 0.01 Hz / s
Used to set the frequency changing rate when the frequency is set with the
external Up/Down terminals or the ▲/▼ keys of the operating panel.
S3.12
Brake unit threshold Factory Default 770 V
Setting range 600 − 785 V Minimum unit 1 V
S3.13
Brake hysteresis voltage Factory Default 10 V
Setting range 5 − 20 V Minimum unit 1 V
● Only for models with a built-in brake unit.
● A suitable brake voltage set via ‘Brake unit threshold’ [S3.12] executes a
fast brake to stop.
● In deceleration or breakdown braking process, the brake function is de‐
activated when DC voltate is larger than ‘Brake unit threshold’ [S3.12]
and smaller than (‘Brake unit threshold’ [S3.12] - ‘Brake hysteresis volt‐
age’ [S3.13]).
S3.14
Motor standard rotation direction Factory Default 0
Setting range 0, 1, 2 Minimum unit
Used to change the standard rotation direction of the motor, same like adjust‐
ing any two wires (U, V and W) of the motor.
●
0: Standard motor direction
● 1: Reverse standard motor direction
● 2: Deactivate reverse motor rotation
S3.15
Stop key validity Factory Default 1
Setting range 0, 1 Minimum unit 1
● 0: Valid only for operating panel control
