4.4 Detailed description of signals (devices)

4.4.1 Forward rotation start Reverse rotation start Temporary stop/Restart

(1) A forward rotation start (RYn1) or a reverse rotation start (RYn2) 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 (RXn0).
(2) A start in the servo amplifier is made when a forward rotation start (RYn)1 or a reverse rotation start
(RYn2) changes from OFF to ON. The delay time of the servo amplifier's internal processing is max.
5ms. The delay time of other signals is max. 10ms.
(3) When a programmable controller is used, the ON time of a forward rotation start (RYn1) or a reverse
rotation start (RYn2)
(4) During operation, the forward rotation start (RYn1) or reverse rotation start (RYn2) is not accepted.
The next operation should always be started after the rough match (RXn2) is output with the rough
match output range set to "0" or after the movement finish (RXnC) is output.
