FX Series Positioning Controllers
PARA. 7: Backlash compensation (Valid exclusively for the cod 00 instruction.)
When the rotation direction is reversed by the cod 00 (DRV) instruction, the compensation
quantity set to this parameter is automatically added to the travel quantity, then positioning is
performed. However, the compensation quantity is not added to the present value register.
When you operate the machine by the cod00 (DRV) instruction immediately after turning on
the power, the machine corrects the backlash while regarding the case as the situation after
operation in the direction in which the current value increases.
• The machine does not perform interpolation while the cod00 instruction sets an operation in
the direction in which the current value increases.
• The machine performs interpolation while the cod00 instruction sets an operation in the
direction in which the current value decreases.
When you operate the machine by any instructions other than an instruction for JOG operation,
instruction for returning to the zero point or the cod00 instruction immediately after turning on
the power, the machine corrects the backlash for an operation just before the cod00 (DRV)
instruction when reversing the rotation direction.
Other compensations as follows can be performed in the positioning program.
Cod73 (MOVC):Travel compensation, cod74 (CNTC):Center point compensation, cod75
(RADC):Radius compensation, cod76 (CANC):Cancel of compensation (except the backlash).

Mechanical system of units:0 to 65,535
Motor system of units
*1: The unit is decided by PARA.3. The pulse conversion value must become 65,535 PLS or less.
PARA. 8: Acceleration time
Set the time required to achieve the maximum speed.
Table 4.12: Acceleration time
When PARA. 8 is set to "0", the machine actually accelerates in 1 ms.
PARA. 9: Deceleration time
Set the time required to stop the machine.
Table 4.13: Deceleration time
When PARA. 9is set to "0", the machine actually decelerates in 1 ms.
