See the next page.
Start
Select any of V/F control, Advanced magnetic flux vector control, Real
sensorless vector control (speed control), or vector control (speed control) to
perform winding with dancer control.
Refer to page 22 for gain adjustment of speed control with Real sensorless
vector control/Vector control.
Setting with pulse train input
(terminal JOG)

Set parameters below according to
the input pulse frequency.
Pr. 384 Input pulse division scaling

Pr. 385 Frequency for zero input pulse
= "0r/min"
Pr. 386 Frequency for maximum input
pulse = "Maximum speed"
Pr. 703 Minimum number of input
pulse = "0"
Pr.704 Maximum number of input pulse
= "Maximum number of pulses"
Set X83 signal ON to activate dancer control.
Set Pr. 128 = "40" to accelerate when dancer roll position detection signal
(terminal 1 input
Set Pr. 128 = "41" to accelerate when dancer roll position detection signal
(terminal 1 input
) with Pr. 128 PID
