3. SIGNALS AND WIRING

3.4 Detailed description of signals (devices)

3.4.1 Forward rotation start Reverse rotation start Temporary stop/Restart

(1) A forward rotation start (ST1) or a reverse rotation start (ST2) should make the sequence which can

be used after the main circuit has been established. These signals are invalid if it is switched on before
the main circuit is established.

Normally, it is interlocked with the ready signal (RD).

(2) A start in the servo amplifier is made when the external start signal changes from OFF to ON. The

delay time of the servo amplifier's internal processing is max. 3ms. The delay time of other signals is
max. 10ms.

Servo motor speed

Forward rotation start (ST1)

or reverse rotation start (ST2)

3ms or less

5ms or more

Temporary stop/Restart (STP)

10ms

or less

(3) When a programmable controller is used, the ON time of the start/stop signal should be 5ms or longer

to prevent a malfunction.

(4) During operation, the forward rotation start (ST1) or reverse rotation start (ST2) is not accepted. The

next operation should always be started after the Movement complete (PED) is output.
