ENABLE
When the control is in RUN, JOG (either
direction) or in the process of ramping to a
stop, this signal should be < -22 VDC. When
the Emergency Stop has been activated, or the
control has Ramped to a stop, then this signal
should be > +14 VDC.
ISOLATED CURRENT FEEDBACK
This is the scaled current feedback signal
which is used to create an error signal for the
current integrator.
SCALED ARMATURE FEEDBACK
The armature voltage signal selected by J3 on
the power board is scaled to an 8 volt level and
used for velocity feedback in the AFB mode,
for zero speed sensing and for control of the
ACCEL/DECEL circuits. The polarity is the
same as the armature voltage polarity.
SCALED TACHOMETER FEEDBACK
The tachometer voltage selected by J8 on the
control board is scaled to an 8 volt level at
motor base speed and used for velocity
feedback in the TFB mode.
SCALED ENCODER FEEDBACK
The 300 PPR encoder signal is scaled to 8
volts.
SCALED BIPOLAR VELOCITY
FEEDBACK
This signal is primarily used to create a
velocity error signal so that the speed can be
controlled. It is also used for zero speed
sensing.
VELOCITY INTEGRATOR
This is the Velocity loop output and the torque
demand signal.
CURRENT INTEGRATOR
This is the Current loop output and the
conduction angle reference.
IR COMPENSATOR
This test point shows the set point of the IR
Comp.
ZERO SPEED OUT
If this signal is > +14 VDC, then the zero
speed circuits are active.
CIRCUIT COMMON
The unisolated common test point provides a
reference point for all of the following signals.
