2-2-5 FWD inhibit and REV inhibit
The HA-655 driver provides [FWD inhibit] and [REV inhibit] input signal ports.
[FWD inhibit]: opening (OFF) the input inhibits forward rotation.
[REV inhibit]: opening (OFF) the input inhibits reverse rotation.
Opening (OFF) both inputs inhibits all rotation.
The inputs may be used to limit the motion range between limit sensors.
● Connection
Refer to [CN2-1: input signal common], [CN2-4: FWD inhibit], and [CN2-5: REV common].
2-2-6 In-position
In the position mode, even though the driver controls the actuator to make the [error count 0], it is not
always possible due to the influence of external forces, acceleration, and deceleration. Establishing a
positioning allowance is a good solution to the problem; that is [in-position range].
[Tune mode]→[4: in-position range] sets the allowance. The actuator position comes within the range
calculated with the formula below, the [CN2-33: in-position] signal outputted.
