NOTE

Jog operation programmed by d10 can only be initiated while the motor is stopped. (Refer to Pr.1-13,

Pr.1-14.)

d11 Acceleration/Deceleration Speed Inhibit:

Parameter value d11 programs Multi-Function Input Terminal: M1 (Pr.4-04), M2 (Pr.4-05), M3 (Pr.4-

06), M4 (Pr.4-07) or M5 (Pr.4-08) for Acceleration/deceleration Inhibit. When the command is

received, acceleration and deceleration is stopped and the AC drive maintains a constant speed.
