Name
Origin search/return initial speed 00000000 to 000186A0 hex
Origin return target speed
Origin return acceleration rate
Origin return deceleration rate
Sets the motor's starting speed when the origin return is executed. Specify
the speed in the number of pulses per second (pps).
Sets the motor's target speed when the origin return is executed. Specify the
speed in the number of pulses per second (pps).
Sets the motor's acceleration rate when the origin return operation starts.
Specify the amount to increase the speed (Hz) per 4-ms interval.
Sets the motor's acceleration rate when the origin return function is decelerat-
ing. Specify the amount to decrease the speed (Hz) per 4-ms interval.
ORG(889)
P
C
Note An instruction execution error will occur if the origin is not determined (relative
coordinate system) when ORG(889) is executed to perform an origin return
operation.
1. Starting Speed for Origin Search and Origin Return
2. Origin return target speed
3. Origin return acceleration rate
4. Origin return deceleration rate
• Outputs: Use either the CW/CCW method or Pulse +
direction method. The same method must be used
for both pulse output 0 and pulse output 1.
• Various origin return parameter settings
• Execution of ORG(889)
To specify the origin return operation, set bits 12
to 15 of the second operand to 1 hex.
(0 Hz to 100 kHz)
00000001 to 000186A0 hex
(1 Hz to 100 kHz)
