• Sets the speed for switching front the first—step to the second—step acceleration/deceleration
in two-step acceleration/deceleration.
• Allowable setting range: 0 to 65535 [ x 100 reference units/s]
• Sets the time of running average for S-curve acceleration/deceleration.
• This constant is used for S-curve acceleration/deceleration.
• Allowable setting range: 0 to 5100 [ x 100 j.ts]
• Running average is not valid when "0" is set.
• Sets bias to change linear acceleration/deceleration to exponential acceleration/deceleration.
• Allowable setting range: 0 to 32767 [ x 500 reference units/s]
• Sets the time constant to change linear acceleration/deceleration to exponential acceleration/
deceleration.
• Allowable setting range: 0 to 5100 x 100 las]
• Exponential acceleration/deceleration is not valid when "0" is set.
• Sets the approach speed for returning to the zero point after the deceleration limit switch sig-
nal turns ON.
• Allowable setting range: 0 to 65535 [ x 100 reference units/s]
• Sets the speed to search for the zero point after the deceleration limit switch signal turns ON
or OFF.
