6.1.16 Cam position compensation time constant
POINT
Use C_CPCD (Cam position compensation request (bit 13 of 2D02h)) to input a
cam position compensation request via the Modbus RTU communication. Use
S_CPCC (Cam position compensation execution completed (bit 13 of 2D12h)) to
read the output status of Cam position compensation execution completed.
C_CPCD and S_CPCC are available with servo amplifiers with software version
C1 or later. For details, refer to "MR-JE-_A Servo Amplifier Instruction Manual
(Modbus RTU communication)".
The compensation amount calculated when cam position compensation is requested is divided into the time
set in [Cam control data No. 61 Cam position compensation time constant] and used for compensation.
