BI-POLAR
ABSOLUTE (STANDARD)
The position of this jumper determines the kind of dc voltage proportional to current that is a
diagnostic signal at the (CUR) output of the I/O connector. With the shorting pin in the bipolar
position, the output CUR signal is plus for positive current and minus for negative current. The
voltage range is plus and minus ten where ten equals the amplifiers continuous current. With
the jumper in absolute, the proportional voltage is always positive for either plus or minus
motor current.
JP4
SLOW (STANDARD)
AT SPEED
The position of this jumper determines the type of output at the I/O terminals (SLOW) output.
In the slow position, the output turns ON if the tac voltage is low, indicating slow speed and
safe to alter amplifier and motor speed select inputs. When the jumper is at the at speed
position, then the operation of the slow output is altered so that it is ON if the ramp generator
output equals the ramp command inputs. This would mean that the motor is at the command
speed.
