• Switching between two different required values
External switching between two connected required value signals (e.g.: between voltage and current signal
input) by closing digital input 1 (X3/9-10).
In ACTUATOR mode the drive can switch between two different frequencies from the digital inputs. The
input signals (current or voltage) will be proportional to the frequency.
(For programming see SUBMENU REQUIRED VALUES [0800].)
• Actual value – Frequency Indicator
e.g. to display the actual motor frequency
How to program see SUBMENU OUTPUTS [0700].
