J2-23 SHARE A: Make no connection
J2-24 SHARE B: Make no connection
J2-25 SHARE C: Make no connection
J2-26 MRC: This is the input signal to the phase C amplifier from the internal
oscillator drive signal. Do not make any connection to this pin except for
troubleshooting.
J2-27 MRA: This is the input signal to the phase A amplifier from the internal
oscillator drive signal. Do not make any connection to this pin except for
troubleshooting.
J2-28 CSC: Current sum for the phase C output. Make no connection to this pin.
J2-29 CSA: Current sum for the phase A output. Make no connection to this pin.
J2-30 OSC C: This is the output from the internal phase C oscillator. Use this pin
as an input if an oscillator is not installed. 5.0 VRMS on this pin will
generate a full-scale output voltage.
J2-31 OSC A: This is the output from the internal phase A oscillator. Use this pin
as an input if an oscillator is not installed. 5.0 VRMS on this pin will
generate a full-scale output voltage.
J2-32 CL C: A DC level from the oscillator used to set the current limit for phase C.
Make no connection to the pin.
J2-33 CL A: A DC level from the oscillator used to set the current limit for phase
A. Make no connection to the pin.
J2-34 D COM: Digital common.
J2-37 FLT B: Make no connection.
J2-38 FSTB HI: Function Sync High signal. This is the collector lead of an
optically isolated NPN transistor. The internal power controller turns this
transistor on to indicate a change of programmed values. This output will
sink more than 2 milliamps to a TTL low logic output level (<.4 volts). The
output is an open collector optocoupler output. A pull-up resistor, customer
supplied, to a + VDC must be connected to J2, pin 38. J2, pin 14, is the
common output. Refer to Figure 3-3.
