JP3 0 to 100VDC Input Range
TEST POINTS
TP1 - +5V Ground
This is used when checking signal levels at the J3 header.
TP2 - +12V Isolated Ground
This is used when checking signal levels on the headers J5 and J6.
TP5 & TP6 - Tachometer Voltage
This is the signal which is being received from the tachometer connected to the drive motor. The voltage
readings should match those at the tachometer.
TP7 & TP8 - Motor Control Voltage
This is the voltage level being sent to the motor control module. It should be a -10VDC to +10VDC signal.
TP9 - Analog Common
This is the analog common from the 9700-10 board. You should use this when measuring signals at TP10
and TP11.
TP10 - Tachometer Signal
This is the signal which is being received from the tachometer connected to the drive motor. The signal has
been scaled by the jumpers JP1-3. This signal is then sent to the 9700 -10 board and read into the
processor.
TP11 - Motor Control Signal
This signal is from the microcontroller, it will be isolated and sent to the motor control module.
TP12 - Remote Speed Signal
This checks that the remote speed signal, 0 to 5VDC will be proportional to the speed signal.
