Output signals circuit
All output signals of the driver are photocoupler/open-collector outputs.
ON voltage: 1.6 VDC maximum
External power supply: 4.5 to 30 VDC, 100 mA or less (5 mA or more for the SPEED-OUT output)

Changing the logic level setting of output signals
The logic level setting for output terminals OUT0 and OUT1 can be changed using the
MEXE02
or operation panel.
However, if the SPEED-OUT output is assigned, it cannot be changed.
Refer to the USER MANUAL for details.
Note
•
Be sure to suppress a current owing to the output circuit to 100 mA or less. Connect a current limiting resistor
externally if the current exceeds this specied value. If the power supply voltage is connected to the output circuit
directly without connecting a current-limiting resistor in between, the driver will be damaged.
•
When connecting a relay (inductive load), etc., to detect alarm outputs, provide
a y-back voltage control measure based on diode, etc., for the inductive load.
Or use a relay with built-in ywheel diode.

When using a controller with a built-in clamp diode
If a controller with a built-in clamp diode is used, a leakage path may form
and cause the motor to rotate even when the controller power is turned
o, as long as the driver power is on.
Since the current capacity of the controller is dierent from that of the
driver, the motor may rotate when the controller and driver powers are
turned on or o simultaneously.
When powering down, turn o the driver power rst, followed by the
controller power, and when powering up, turn on the controller power rst,
followed by the driver power.

5. Connecting external analog setting devices
Using an external potentiometer (sold separately) or external DC voltage, the analog setting for the rotation speed or torque
limiting value can be performed.
Refer to p.28 and p.29 as well as the USER MANUAL for the setting method.

Using external DC voltage
For the external voltage, use a DC power supply (0 to 10 VDC) with reinforced
insulation on its primary and secondary sides, and connect to the pin Nos. 13
and 14 of CN5.
The input impedance between the VM input and VL input is approximately
41.8 k
Ω
.
The VL input is connected to IN-COM1 inside the driver.

Note
Be sure to use the external DC voltage at 10 V or lower. When connecting the external DC power supply, make sure the
polarities are correct. Reversing the polarities may cause damage to the driver.
