Code Display Description Range Unit Default
DIO_47 ZSD Level Zero Speed Detect Level 0.0 ~ 480.0 rpm 10
DIO_48 ZSD Band ZSD hysteresis band 0.1 ~ 10.0 % 0.5
z DIO_48(ZSD Band) is set as the percentage of FUN_04 Max motor speed.
2.4) Spd Det. – Polarity valid
2.5) Spd Det.(ABS) – Polarity invalid
This is ON when the real motor speed reaches the arbitrary speed. The polarity of detecting speed is valid for Spd Det.
But, the polarity is invalid for Spd Det(ABS).
Code Display Description Range Unit Default
DIO_49 SD Level Speed Detect Level -3600 ~ 3600 rpm 0
DIO_50 SD Band Speed Hysterisis Band 0.1 ~ 10.0 % 0.5
