Spindle control output 4
bit0. Current detection (CD)
This signal turns ON when the start signal (forward run, reverse run, orientation) is ON, and the
current flowing to the motor is approx. 110% or more of the rating. (The motor output (current)
guarantee value is 120% of the rating.)
bit1. Speed detection 1 (SD1)
This signal turns ON when the motor speed drops below the value set with parameter SP020
(SDTS). The ON to OFF hysteresis width is set with parameter SP047 (SDTR). This signal turns
ON when the motor's speed is less than the set speed regardless of the input signal state.

bit2. Up-to-speed (US)
This signal turns ON when the start command signal (forward run, reverse run) is ON, and the
motor speed has reached a range of ±15% (standard value) of the speed command value. This
signal turns OFF when the start command signal turns OFF. The up-to-speed output range can b e
set with the parameter SP048 (SUT). Even though the setting value is small, the output will be
±45r/min. Pay attention when speed command value is small.

bit3. Zero speed (ZS)
Regardless of the input signal state, this signal turns ON when the motor speed drops below the
value set with parameter SP018 (ZSP). Once this signal turns ON, it will not turn OFF for at least
200ms. When switching ON to OFF, hysteresis width is 15r/min. Note that if the parameter SP018
(ZSP) setting value is too small (approx. 10r/min or less), this signal may not be output even if the
motor is stopped.
