1)  GND (Pin 8) and COM- (Pin 13) of CN1 connector are independent respectively and do not have 

connection with the ground terminal outside the servo drive. 

The Tables 3.A, 3.B, & 3.C detail the three groups of signals of the CN1 interface. Table 3.A details the 

general signals. Table 3.B details the Digital Output (DO) signals and Table 3.C details the Digital Input 

(DI) signals. The General Signals are set by the factory and can not be changed, reprogrammed or 

adjusted. Both the Digital Input and Digital Output signals can be programmed by the users. 

V_REF 9 

Motor speed command: -10V to +10V, corresponds to 
the maximum speed programmed P1-55 Maximum 
Speed Limit (Factory default 3000 RPM).

T_REF 6 

Motor torque command: -10V to +10V, corresponds 
to -100% to +100% rated torque command.

The drive can accept two different types of pulse 
inputs: Open Collector and Line Driver. 
Three different pulse commands can be selected via 
parameter P1-00. Quadrature, CW + CCW pulse & 
Pulse / Direction.

The motor encoder signals are available through 
these terminals. The A, B, Z output signals can be 
Line Driver type. The Z output signal can be Open 
Collector type also, but the output maximum voltage 
is 5V and the maximum permissible current is 
200mA.

VDD 7 

VDD is the +24V source voltage provided by the 
drive. Maximum permissible current is 500mA.

COM+ is the common voltage rail of the Digital Input 
and Digital Output signals. Connect VDD to COM+ for 
source mode. For external applied power sink mode 
(+12V to +24V), the positive terminal should be 
connected to COM+ and the negative to COM-.

The Digital Input (DI) and Digital Output (DO) have factory default settings which correspond to the 

various servo drive control modes. (See section 1.5). However, both the DI's and DO's can be 

programmed independently to meet the requirements of the users. 

Detailed in Tables 3.B and 3.C are the DO and DI functions with their corresponding signal name and 

wiring schematic. The factory default settings of the DI and DO signals are detailed in Table 3.F.
