1.3.5 High-precision Synchronous Control
Various types of position data can be monitored and SERVOPACK parameters can be
changed at high speed during machine operation. This data can be used for high-precision
synchronous control by executing READ and WRITE in ladder logic programs or motion
programs.
• Mode Changes during Operation
The mode can be changed to position control, torque control, speed control, or synchro-
nous phase control during operation.
• Various Operation Commands
Speed loop P/PI switching, external torque control, and speed limits for torque control
can be specified from the MP940 during operation.
• Read/Write SERVOPACK Parameters
User-set SERVOPACK parameters, such as position loop gain, speed loop gain, speed
loop integral time constant, and so on, can be changed during operation.
• Position Data Monitoring
Position data, command speeds, speed monitoring, and external encoder data can be ref-
erenced at high speed by the program.
