Appendix A
Performance Characteristics
The performance characteristics of the CJ1W-NCF71 are described here.
Refer to these characteristics when building applications.
The numerical values for each performance characteristic are obtained using the following machines and con-
figuration.
CPU Unit: CJ1H-CPU
@@
H (without an Expansion Rack)
Position Control Unit: A single PCU installed on the CPU Rack.
Servo Drive: R88D-WT01HL Servo Drive equipped with a FNY-NS115 MECHATROLINK-II I/F Unit
Note The performance values shown in this Appendix will depend on conditions such as the CPU Unit, user
program, and other installed Units used. Therefore, these values are for reference purposes only.
Power Up Time
When the PCU is powered up or restarted, the time required for the Unit to complete its initial processing and
be ready to receive commands from the CPU Unit is 500 ms max.
The Unit Busy Flag turns ON during initial processing after turning ON the PCU power or restarting the Unit.
Command Response Time
The PCU's command response time is the time from when the CPU Unit (user program) sends a command to
the PCU until the Servo Drive actually starts operating in response to the command, and the changes in Servo
Drive, such as the present position and statuses are reflected in the CPU Unit's user program.
The command response time depends on the CPU Unit's cycle time, MECHATROLINK's transfer time and
communications cycle, and the command processing time of MECHATROLINK slave station device.
