Input and output signals
When the motor have a tachogenerator you can use the terminal 9ac as input for this feedback.
Connect this terminal to the negative of tachometer.
On this terminal is available analog output "current monitor of motor" with range 0V + /-8V. The value
of 8V is the maximum current supplied by the drive. For example, if we have a size 7/14A, 8V
corresponds at 14A circulating on the motor.
The signal can be positive or negative depending on the direction of rotation of the motor.
In the terminals CHA and CHB (on the rack or panel-mounting) can connect the inputs from an
incremental encoder for the current feedback in response to encoder. signals can come from
encoder powered from +5 V to +24 V).
Minimum high logic level > +2.8 V/24Vmax,
Minimum low logic level <1.5V
Encoder can be connected either push-pull (wires A, B and GND) or line-driver encoder type (wires
+ A + B and GND). Remember to connect the zero encoder with the GND signal converter.
