Input/Output Interface: Analog Signals
Velocity Command Input -- Differential input 0 to ±10 Vdc (15 Vdc Max)
Auxiliary Input --- Differential input 0 to ±10 Vdc (15 Vdc Max)
Velocity Output --- Select 1.25, 2.07, 3.71, or 4.54 volts per 1000 rpm
Current Output ---- ±10 volts = ± Peak Current
The AMC drive i have is a is a 25A8 , it has 2 current output lines.
CURRENT MONITOR
Current Monitor. Analog output signal proportional to the actual current output. Scaling is 4.4 A/V. Measure relative to signal ground.
CURR REF OUT
Measures the command signal to the internal current-loop. This pin has a maximum output of ±7.25 V when the drive outputs maximum peak current.
Measure relative to signal ground
Al, are you familiar with the CURR REF OUT and what it does ?
