CONTROL MODE

Control mode [G] [WG]
The method for driving a servo motor varies depending on each control mode. The characteristics of each control mode are
shown in the following.
*1 Available on servo amplifiers with firmware version A5 or later.
*2 Available on servo amplifiers with firmware version B0 or later.
Control switching
In the motion mode, the control mode can be switched with [Modes of operation (Obj. 6060h)]. Switching the control modes
with [Modes of operation (Obj. 6060h)] applies to the cyclic modes (csp, csv, and cst), profile modes (pp, pv, and tq), homing
mode (hm), and continuous operation to torque control mode (ct).

Description
CiA 402 control mode
Cyclic synchronous position
mode
csp
This is a control mode to drive servo motors by receiving a position
command at a constant period in the synchronous communication with a
controller.
Use an absolute position address for the command.
Cyclic synchronous velocity
mode
csv
This is a control mode to drive servo motors by receiving a speed
command at a constant period in the synchronous communication with a
controller.
Cyclic synchronous torque mode
cst
This is a control mode to drive servo motors by receiving a torque
command at a constant period in the synchronous communication with a
controller.
Profile position mode
pp
This is a positioning mode to drive servo motors by receiving an end
position command via either synchronous or asynchronous
communication with a controller.
Use an absolute position address or a relative position address for the
command.
Profile velocity mode
pv
This is a control mode to drive servo motors by receiving a target speed
command via either synchronous or asynchronous communication with a
controller.
Profile torque mode
tq
This is a control mode to drive servo motors by receiving a target torque
command via either synchronous or asynchronous communication with a
controller.
Homing mode
hm
This is a control mode to perform homing with the method specified by the
controller.
Thrust/torque control
Continuous operation to torque
control mode
ct
This function enables smooth switching to torque control from the position
control mode or speed control mode without stopping the servo motor.
This eliminates rapid change of speed and torque, contributing to
reduction in load to the machine and high-quality product molding.
