A connection example is given in the figure below.
I/O connection

In addition to the driver’s internal potentiometer, an external poten-
tiometer or external DC voltage may also be used to set the motor’s
operating speed. Two operating speeds can be set using the inter-
nal potentiometer together with an external potentiometer or exter-
nal DC voltage.
Acceleration/deceleration rates can be set independently.
Additionally, a jerk-limit control time can be set to suppress vibration
during acceleration/deceleration.
Setting
■
Setting the operating speeds with the internal
potentiometer
The internal potentiometer is used when the set operating speed is
not changed frequently, or when operating the motor at two speeds
using an external potentiometer concurrently with the driver’s inter-
nal potentiometer. The speed setting range is between 0 and 1500
r/mn. VR-H, VR-M and VR-L need not be connected if the operat-
ing speed is set using the internal potentiometer alone.
■
Setting the operating speeds with an external
potentiometer
An external potentiometer is used when setting the speed at a dis-
tance from the driver, or when operating the motor at two speeds us-
ing the internal potentiometer concurrently with an external poten-
tiometer. The speed setting range is between 0 and 1500 r/min. Use
the optional part
PAVR-20KZ
(sold separately) for external speed
setting. Turning the potentiometer clockwise increases the set speed.

■
Setting the operating speeds via external DC
voltage
External DC voltage is used when setting a speed via the D/A out-
put of a programmable controller, or when operating the motor at two
speeds using the internal potentiometer concurrently. The speed
setting range is between 0 and 1500 r/min For external DC voltage,
use a DC power source (0 to 5 VDC, 1 mA or more) with reinforced
insulation provided on the primary and secondary sides.
To operate the motor at the
speed set with an external po-
tentiometer, turn the EXTVR in-
put to ON.
To operate the motor at the speed set via external DC voltage, turn
the EXTVR input to ON.
