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 search speed for the zero point after the deceleration limit switch signal turns ON
or OFF.
D Allowable setting range: 0 to 65535 [× 100 reference units/s]
J Cn-0028: Final Travel Distance To Return To Zero Point
D Sets the distance from the encoder zero point pulse (phase-C pulse) to the zero point when
returning to the zero point.
D Allowable setting range: −2147483648 to +2147483647 [reference units]
D If the setting distance is reverse direction or a short travel distance, the motor will decelerate
to a stop and then return to reverse direction.
J Cn-002A: Zero Point Width
D Sets the zero point (ZPOINT) detection width.
D Allowable setting range: 0 to 65535 [reference units]
J Cn-0033: Absolute Encoder Zero Point Offset
D Sets the difference between the encoder zero point (position 0) and the machine zero point
if an absolute encoder is used. For example, set the amount of offset so that the machine zero
point is position 0.
D Allowable setting range: −2147483648 to +2147483647 [reference units]
J Cn-002B: Final Travel Distance for External Positioning
D Sets the distance from the external signal input during external positioning.
D Allowable setting range: −2147483648 to +2147483647 [reference units]
D If the setting distance is reverse direction or a short travel distance, the motor will decelerate
to a stop and then return to reverse direction.
J Cn-002F: Forward Software Limit
D Sets the forward software position limit.
