Signals connector - J3 (MBA-DBP/3UE and MBA-DBP/6UE)

Pin	Function				Remarks
1	positive	input	of	a	See Appendix C.
	differential amplifier.
2	Negative	input	of	a	See Appendix C.
	differential amplifier.
3	Output	of		a	See Appendix C.
	differential amplifier.
4	Circuit common
5	Analog input				This input is monitored by the main μP. When Vi
					< 5V, R1=470ohm should be inserted. When Vi>
					5V, R1(Kohm)=2Vi-10 should be inserted. The	μP
					always reads a range of +5V.
6	Circuit common
7	Circuit common
8	Current monitor				This analog output represents the actual current
					in the motor. The scale (in A/V) is: Ip / 7.5
					Ip - Rated peak current of amplifier.
9	Circuit common
10	+5V output				There are several +5V pins. The accumulative
					external load should not exceed 200mA.
11	+15V output				There are several +15V pins. The accumulative
					external load should not exceed 100mA.
12	-15V output				There are several -15V pins. The accumulative
					external load should not exceed 100mA.
13	Channel B output
14	Channel A output
15	Index output				For resolver option only.
16	Not connected
17	Inhibit output				Relay contact (potential free).
					The relay contact is closed whenever	the
					amplifier is enabled. Contact rating: 0.5A, 200V,
					10W.
