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.
