4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Reverse run control mode
[Function]
This signal is used to save the reverse run information used for the reverse run control in the arbitrary reverse run.
[Operation]
When this signal is ON, the reverse run information is saved.
Turn this signal ON at the start of the block where the reverse run control is executed and turn it OFF at the time of reset.
Turn ON the "Recalculation request" signal (CRQ) when this signal is turned ON.
When a recalculation request is not made, blocks already created by pre-reading are not retained as reverse run
information.
[Related signals]
(1) Reverse run from block start (RVSP: YD08)
(2) Macro interrupt priority (RVIT: YD09)
(3) Reverse run (VRV: YC27)
(4) Recalculation request (CRQ: YC2B)
Cont. Signal name
Rapid traverse time constant: Switcho-
A
ver request
[Function]
The rapid traverse time constant can be switched over.
1: Switch the rapid traverse time constant of all axes in the part system to the axis specification parameter "#2598
G0tL_2", and switch the rapid traverse time constant (primary delay)/second-step time constant for soft
acceleration/deceleration to the axis specification parameter "#2599 G0t1_2".
0: Switch back the rapid traverse time constant of all axes in the part system to the axis specification parameter "#2004
G0tL", and switch back the rapid traverse time constant (primary delay)/second-step time constant for soft
acceleration/deceleration to the axis specification parameter "#2005 G0tL".
[Operation]
When this signal is turned ON (1), the NC operates as follows:
 When any of the axes in the part system is moving, the time constant is switched after all the axes in the part system
have decelerated to a stop.
 When any of the axes in the part system is at a standstill, the time constant is switched immediately.
When this signal is turned OFF (0), the NC operates as follows:
 When any of the axes in the part system is moving, the time constant is switched back after all the axes in the part sys-
tem have decelerated to a stop.
 When any of the axes in the part system is at a standstill, the time constant is switched back immediately.

Cont. Signal name
Real-time tuning 2: Acceleration/decel-
A eration time constant in automatic swi-
tchover
[Function]
This signal automatically switches acceleration/deceleration time constant in the real-time tuning 2 function.
[Operation]
While this signal is ON, the acceleration/deceleration time constant is always switched to a value based on the current
estimated inertia ratio.
While this signal is OFF, the switching process is not performed for the acceleration/deceleration time constant.
