Inputs and outputs
When the drive is in external control, the following analog and digital inputs/outputs
can be used to control the drive.
 Analog inputs
The drive has two programmable analogue inputs, AI1 and AI2. Both inputs can be
used either as a voltage input or current input (-11…11 V or -22…22 mA). Both inputs
can be filtered and scaled. The input type is selected with jumpers J1 and J2 on the
JCU Control Unit, respectively. The inaccuracy of the analogue inputs is 1% of the full
scale range and the resolution is 11 bits (+ sign). The hardware filter time constant is
approximately 0.25 ms.

 Analog outputs
The drive has two programmable analogue outputs: one current output AO1 (0…20
mA) and one voltage output AO2 (-10…10 V). Both outputs can be filtered and
scaled. The resolution of the analogue outputs is 11 bits (+ sign) and the inaccuracy is
2% of the full scale range. The analogue output signals can be proportional to, eg,
motor speed, process speed (scaled motor speed), output frequency, output current,
motor torque, and motor power. It is also possible to write a value to an analogue
output through a serial communication link (eg, a fieldbus link).
