CONTROL OPTIONS
The direction of rotation for slave motors is determined by [IVS] and the pulse input format.
Table 6.2.13
(1) (2) (3) IVS Slave direction of operation
B-phase high A-phase input B-phase, 90° advance OFF Forward
B-phase high A-phase input B-phase, 90° advance ON Reverse
B-phase low B-phase input B-phase, 90° delay OFF Reverse
B-phase low B-phase input B-phase, 90° delay ON Forward
Pulse input format
(1) Command pulse/command code
(2) Forward run pulse/reverse run pulse
(3) Two signals with a 90° phase difference
Select the pulse input format with function code o13.
6.2.5.2 Synchronized operation method
• Manipulate the [FWD] terminal and [SYC] (the contact input terminal) simultaneously during pulse train
operation.
• When [FWD] turns on with a delay after [SYC] turns on while a pulse train continues to be input, the motor
may accelerate to its maximum speed in order to eliminate the accumulated deviations.
Risk of bodily injury
• Operating the motor with an incorrect allocation of the function selection input function code's data may result
in bodily injury or equipment damage. Re-check allocation prior to operation.
Risk of equipment damage
Synchronized operation signal [SYC]
During pulse train operation, allocate one of the contacts X1 to X14 to 27 (SYC) for the slave motor and
manipulate [SYC] together with the [FWD] signal.
Table 6.2.14
Function code Function name Pulse train function
E01 to E13
X1 to X14 function
selection
In order to perform position control operation, allocate the synchronized
operation instruction ([SYC]: 27) to one of the contact input terminals
listed to the left.
