Connecting Inputs
Velocity Command Signal (VCS)
Function
This input controls motor speed and direction. When a positive voltage is applied to pin 1 with
respect to pin 2, the motor shaft will rotate CW as viewed from the shaft end of the motor. A
negative voltage applied to pin 1 with respect to pin 2 will result in counterclockwise (CCW)
rotation.
This input signal is conditioned through a differential drive to reduce noise. Proper shielding
is recommended, as shown in Figure 2.7.
Input signal range is ± 10 VDC.
Connection
P1 pin 1 is VCS+
P1 pin 2 is VCS-
Auxiliary Input
Function
The auxiliary input signal (AUX) may be used, in addition to VCS, as a velocity signal.
Refer to the Figure 1.1 on page 1-2.
Input signal range is
±
10 VDC.
Connection
P1 pin 3
Inhibit (INH)
Function
This input signal inhibits or enables the output stage. The input can be either active high or
active low, depending on the position of jumper P8A. (Location of the jumpers on the velocity
regulator board is shown in Figure 2.1.) This input is also used to reset the System Status Output
(SSO) fault circuit. The INHibit input must be activated to clear the SSO fault.
Connection
P1 pin 8
(Refer to “Internal Connections (FAC, RAC and INH)” on page 2-11.)
Forward and Reverse Amplifier Clamps (FAC, RAC)
Function
The forward amplifier clamp (FAC) and reverse amplifier clamp (RAC) are directional clamps
that will operate in one of two ways, depending on the position of jumpers P6 and P7. With P6
and P7 in the FAC ILIMIT and RAC ILIMIT positions, the drive will limit the current to 5% of
peak current in the corresponding direction, allowing operation in the opposite direction, when
either clamp is activated. With P6 and P7 in the FAC DISABLE and RAC DISABLE positions,
there will be no torque in the corresponding direction when either clamp is activated.
Forward is defined as CW motor shaft rotation as viewed from the shaft end of the motor.
Reverse is defined as CCW motor shaft rotation as viewed from the shaft end of the motor.
The FAC and RAC inputs can be either active high or active low, depending on the position of
jumper P8A. Refer to the sourcing and sinking diagrams below for the operation of the jumper
settings. (Location of each jumper on the velocity regulator board is shown in Figure 2.1.)
