Instruction manual
29
J2-1 ANALOG COMMON: This is the common for all analog signals on the
connector.
J2-2 MRB: This is the input signal to the phase B amplifier from the internal
oscillator drive signal. Make no connection to this pin except for
troubleshooting.
J2-3 ANALOG COMMON: See J2-1.
J2-4 CSB: Current sum for the phase B output. Make no connections to the pin.
J2-5 CT COMMON:
J2-6 OSC B: This is the output from the internal phase B oscillator. Use this pin
as an input if an oscillator is not installed. A 5.0 VRMS signal will generate
a full-scale output voltage.
J2-7 ANALOG COMMON: See J2-1.
J2-8 CL B: A DC level from the oscillator used to set the current limit for phase B.
Make no connection to the pin.
J2-9 RPV: No connection.
J2-10 OVR TEMP¯¯¯¯¯¯¯¯¯¯¯ 6: A logic low output to indicate an overtemperature
condition. Make no connection to the pin.
J2-12 FLT C: Make no connections.
J2-13 FLT A: Make no connections.
J2-14 FSTB LO: Function Sync Low signal. This is the emitter lead of an optically
isolated NPN transistor. The internal power controller turns this transistor on
to indicate a change of programmed values.
J2-15 EXT SYNC LO: External Sync Low signal. This is the ground return for the
TTL external sync input. It connects to the cathode of an LED at the input of
an optocoupler. Refer to J2-32.
J2-16 Solid State B: Control the solid state option output switch for Phase B.
J2-17 PARALLEL: No connection.
J2-18 FLT¯¯¯¯ 7: No connection.
J2-19 DFI2:
