Cn-0021
J Cn-0021: Acceleration/Deceleration Constant Switching Speed
D Sets the speed for switching from the first−step to the second−step acceleration/deceleration
in two-step acceleration/deceleration.
D Allowable setting range: 0 to 65535 [¢ 100 reference units/s]
J Cn-0026: Running Average Time
D Sets the time of running average for S-curve acceleration/deceleration.
D This constant is used for S-curve acceleration/deceleration.
D Allowable setting range: 0 to 5100 [¢ 100 µs]
D Running average is not valid when "0" is set.
J Cn-002D: Exponential Acceleration/Deceleration Bias
D Sets bias to change linear acceleration/deceleration to exponential acceleration/deceleration.
D Allowable setting range: 0 to 32767 [¢ 500 reference units/s]
J Cn-002E: Exponential Acceleration/Deceleration Time Constant
D Sets the time constant to change linear acceleration/deceleration to exponential acceleration/
deceleration.
D Allowable setting range: 0 to 5100 [¢ 100 µs]
D Exponential acceleration/deceleration is not valid when "0" is set.
J Cn-0022: Zero Point Return Approach Speed 1
D Sets the approach speed for returning to the zero point after the deceleration limit switch sig-
nal turns ON.
D Allowable setting range: 0 to 65535 [¢ 100 reference units/s]
J Cn-0023: Zero Point Return Approach Speed 2
D Sets the speed to search for the zero point after the deceleration limit switch signal turns ON
or OFF.
