5-2 Speed Control

The CJ1W- and CS1W-NCx71 Position Control Units for MECHATROLINK-II issue the speed
control commands. The Servo Drive uses the commands and rotates the motor in the
commanded speed output. The present value to be fed back from the Servo Drive to the
Controller is the values obtained by dividing the command by the Electronic Gear Ratio
(determined by the settings in Pn009 or Pn010).

Set the acceleration time for internally set speed control. Set
the time until 1,000 r/min is reached.
Set the deceleration time for internally set speed control. Set
the time until 1,000 r/min is reached.
Set the S-curve time in the time width centered on the
inflection points for acceleration and deceleration.
Set the detection threshold for speed conformity output. If
the difference between the speed command and motor
speed is within the set threshold, a speed conformity output
is output.
This setting has a hysteresis of 10 r/min for detection.
Set the detection threshold for speed reached output. A
speed reached output is output when the motor speed
exceeds the set value.
This setting has a hysteresis of 10 r/min for detection.
