3.3.2 Signals Explanation of Connector CN1

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.

Table 3.A General Signals

Signal		Pin No	Details	Wiring Diagram
				(Refer to 3-3-3)
	V_REF	42	Motor speed command: -10V to +10V, corresponds	C1
Analog			to the maximum speed programmed P1-55
Signal			Maximum Speed Limit (Factory default 3000 RPM).
Input	T_REF	18	Motor torque command: -10V to +10V, corresponds	C1
			to -100% to +100% rated torque command.
			The MON1 and MON2 can be assigned drive and
Analog			motor parameters that can be monitored via an
	MON1	16	analogue voltage.
Monitor				C2
	MON2	15	Please reference parameter P0-03 for monitoring
Output
			commands and P1-04 / P1-05 for scaling factors.
			Output voltage is reference to the power ground.
	PULSE	41	The drive can accept two different types of pulse
	/PULSE	43	inputs: Open Collector and Line Driver.	C3/C4
Position			Three different pulse commands can be selected via
	SIGN	37
Pulse			parameter P1-00. Quadrature , CW + CCW pulse &
	/SIGN	36
Input			Pulse / Direction.
	PULL HI	35	Should an Open Collector type of pulse be used this	C3
			terminal must be lulled high to pin 17.
	OA	21
Position	/OA	22
			The motor encoder signals are available through
	OB	25
Pulse			these terminals. The encoder output pulse count can	C11/C12
	/OB	23
Output			be set via parameter P1-46.
	OZ	50
	/OZ	24
	VDD	17	VDD is the +24V source voltage provided by the
			drive. Maximum permissible current 500mA.
Power		11	COM+ is the common voltage rail of the Digital Input	-
	COM+	45	and Digital Output signals. Connect VDD to COM+
			for source mode. For external applied power sink
	COM-	47
			mode (+12V to +24V), the positive terminal should
		49
			be connected to COM+ and the negative to COM-.
			VCC is a +12V power rail provided by the drive. It
	VCC	20	can be used for the input on an analog speed or
			torque command. Maximum permissible current
Power				-
			100mA.
	GND	12,13,	The polarity of VCC is with respect to Ground (GND).
