6.7.3. Analog Inputs – Torque (Pressure) Control
A 0 - 10 V or 4 - 20 mA signal can also be used to control the VFD torque limit setting (parameter 416) from 0 - 100% using
analog input 54. The same wiring schematics from section 6.7.2 apply with the only difference being the use of analog in-
put 54.
The VFD is set to receive a 0 - 10 V input signal as configured from the factory. To change to 4 - 20 mA input signal, toggle
the A54 switch to "U" to "I" inside the VFD.

6.7.2. Analog Input – Speed control
A 0 - 10 V or 4 - 20 mA signal can be used to control VFD speed from 0 - 100% using analog input 53.
The VFD is set to receive a 0-10 V input signal as configured from the factory. To change to 4-20 mA input signal, toggle the
A53 switch from "U" to "I" inside the VFD.
