Motor Current Output (MCO 0-10V)
Function
The motor current output is an analog voltage which is proportional to the motor current. The
scaling of this signal is proportional to the absolute value of the motor current, such that MCO
is 10V when motor current is either 30 amps or -30 amps. See Figure 2.17 on page 2-16.

P2 pin 3 signal
P2 pin 4 or pin 6 reference
Motor Current Output (MCO
±
10V)
Function
The motor current output is an analog voltage which is proportional to the motor current. The
scaling of this signal is ±10 volts = ±30.0 amps (
±
10%). See Figure 2.17 on page 2-16.

P2 pin 7 signal

Motor Velocity Output (MVO)
Function
The motor velocity output (MVO) signal is an analog voltage signal which is proportional to
the actual instantaneous motor speed. The scaling of this signal and the tolerance is dependent
on the voltage constant of the tachometer in use. This output is not affected by the TACH gain
potentiometer. (See “Tach Gain (TACH)” on page 3-3.) In the standard drive-motor interconnec-
tion, this voltage is positive for CW rotation of the motor as viewed from the shaft end of the
motor, and negative for CCW rotation. See Figure 2.7 on page 2-9. This signal is identical to the
MVO test point. (See “Test Outputs” on page 4-5.)
