Select two terminals for up-down operation and set them to ‗19 (Up)‘ and
‗20 (Down)‘, respectively. With the operation command input,
acceleration begins when the Up terminal signal is on. Acceleration stops
and constant speed operation begins when the signal is off.
During operation, deceleration begins when the Down signal is on.
Deceleration stops and constant speed operation begins when both Up
and Down signals are entered at the same time.
During a constant speed operation, the operating frequency is saved
automatically in the following conditions: the operation command (Fx or
Rx) is off, a fault trip occurs, or the power is off.
When the operation command is turned on again, or when the inverter
regains the power source or resumes to a normal operation from a fault
trip, it resumes operation at the saved frequency. To delete the saved
frequency, use the multi-function terminal block. Set one of the multi-
function terminals to 22 (U/D Clear) and apply signals to it during
constant speed operation. The saved frequency and the up-down
operation configuration will be deleted.
