（2）VR(Motor Speed Control Voltage) and VCC (+DC10V Power Source for Analog
Signal)(CN2:Pin10,Pin11,Pin23)
Pin10:Common for Pin11 & Pin23
Pin23:Input Motor Speed Control Voltage (+0-10V DC) on VR
(Motor Speed Control Voltage)
Pin11:+10V DC is output on VCC (+10V DC Power Source for
Analog Signal). Pin11 can be used as a source for Motor
Speed Control Voltage and Motor Speed Rotation can be
varied by varying this voltage. Attach a 50KΩ
Potentiometer.(Refer to
By supplying +10V DC, Motor Speed can be varied up to
80,000min
（3）ERR (Trip Signal Output) (CN2 : Pin8, Pin18)
Photo Coupler isolated Transistor Output .
(Max. Rating of Transistor is V
Pc=100mW) Please use at less than the maximum rating
For NE52, NE137, the trip signal transistor is ON when a
trip signal is output. The Error Output Code from NE147-
needs to be reversed to maintain the compatibility with
NE52, NE137 use the following process.
①Turn the Power Switch OFF
②Remove the top cover from the control unit.
③Turn off No.1 dip switch. DO NOT change any other dip
(Fig.20)
switches.
④Reinstall the top cover.
（4）LOAD (Load Signal) (CN2: Pin12, Pin13)
DC Voltage is output: +0〜15V DC in proportion to Motor
(Fig.21)
Load.
CAUTION
！
Be careful when connecting outputs to other electric equipment, because (-) Voltage may be output. (Fig.21)
（5）STOP (Rotation Stop) (CN2:Pin6, Pin18)
Photo Coupler isolated Transistor Output
When Motor is stopped, Transistor is OFF.
The Max. Rating of Transistor is V
Pc=100mW.
Please use at less than the maximum rating.
CAUTION
！
The transistor will switch ON/OFF repeatedly when motor speed is between 400-1,000rpm take
care when designing control software. Especially, when ON/OFF is cycled rapidly.
