Outline
You can control the speed according to the analog speed command from the host con-
troller or the speed command set in the servo driver.

Function
(1) Velocity control by analog speed command
The analog speed command input voltage is converted to equivalent digital speed
command. You can set the filter to eliminate noise or adjust the offset.

Unit
This driver is equipped with internal speed
0 to 3 — setup function so that you can control the
speed with contact inputs only.
Select the Positive/Negative direction
0 to 1 —
specifying method.
Based on the voltage applied to the
(r/min)
analog speed command (SPR), set up the
/V
conversion gain to motor command speed.
Specify the polarity of the voltage applied
0 to 1 —
to the analog speed command (SPR).
Set up the offset correction value applied
0.359mV
5578 to the voltage fed to the analog input 1.
Set up the time constant of 1st delay filter
0.01ms that determines the lag time behind the
voltage applied to the analog input 1.
