(3) Have you entered the speed reference?
Confirm the speed reference (N*) on the "Operation monitor" when you have
directed the speed reference by the KEYPAD panel, external analog input, or
through the link (T-Link or RS485) or the UPAC. If the "N*" is blank, the inverter
has not received the speed reference.
When you use the analog input [12] to provide the speed reference, you
can check the voltage on the "I/O check" screen of the KEYPAD panel.
Since the displayed voltage is the one the inverter recognizes, you can
check the [12] input on this screen.
When you use the [12] and the value fluctuates, you can check if the
analog reference itself fluctuates.
In the same manner, check the auxiliary speed reference supplied to the analog
input Ai1 and Ai2.
