Interpolation Control Unit - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

• The parameter block No. used in the home position return or JOG operation is set at the setting of the "home position return data" or "JOG operation data"
using MT Developer2. (Page 178 Home Position Return Data, Page 188 JOG Operation Data)
[Home position return data setting screen]
• The processing method of acceleration/deceleration is set by the acceleration/deceleration method and S-curve ratio set in
the parameter block.
• Set "Trapezoid/S-curve" as acceleration/deceleration method to execute the trapezoidal acceleration/deceleration or S-curve acceleration/deceleration. Set
0[%] as S-curve ratio to execute the trapezoidal acceleration/deceleration, and set 1 to 100[%] to execute the S-curve acceleration/deceleration.
• Set "Advanced S-curve" to execute the Advanced S-curve acceleration/deceleration. At this time, the S-curve ratio is invalid.

• When the FIN acceleration/deceleration (Fixed acceleration/deceleration time method) is set in the continuous trajectory control, the setting for advanced S-
curve acceleration/deceleration is invalid.

Interpolation control unit

Set the unit for interpolation control.
The unit is also used as the unit for the command speed and the allowable error range for circular interpolation set by the
servo program or the Motion dedicated PLC instruction (M(P).SVSTD/D(P).SVSTD).
Refer to the control units for interpolation control for details. (Page 256 Control units for interpolation control)
