Unit Description / Notes
- Speed = DIx Open (0 V), Torque = DIx Closed (+24 V).
When Torque is selected the speed regulators gains P161 and P162
are not used and changed to: Gp (Proportional Gain) = 1.00 and Gi
(Integral Gain) = 0.00. Thus the Total Reference becomes the input of
the Torque Regulator. Refer to figure 6.26.
When Speed is selected, the speed regulator gains are defined
again by P161 and P162. In applications with torque control, proceed
as described at P160.
- The Option DC Link Voltage Regulator must be used, when P150 = 2.
Refer to description of parameter P150.
- DI8 is designed to be used as Motor Thermistor (PTC) input on the
option boards EBA/EBB. It can also be used with just one PTC.

- If DI8 should be used as normal digital input - Program the
parameter P270 to the required function and connect a resistor between
270  and 1600  in series with the input 4, as indicated below:
