Start/stop from the operation panel (PU operation)
REMARKS
The initial values of the terminals RH, RM, RL are 60Hz, 30Hz, and 10Hz. (Use Pr. 4, Pr. 5 and Pr. 6 to change.)
In the initial setting, when two or three of multi-speed settings are simultaneously selected, priority is given to the set frequency
of the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
Maximum of 15-speed operation can be performed. (
60Hz for the RH, 30Hz for the RM and 10Hz for the RL are not output when they are turned ON ... Why?
Check for the setting of Pr. 4, Pr. 5, and Pr. 6 once again.
Check for the setting of Pr. 1 Maximum frequency and Pr. 2 Minimum frequency once again. (Refer to page 45)
Check that Pr. 180 RL terminal function selection = "0", Pr. 181 RM terminal function selection = "1", Pr. 182 RH terminal function
selection = "2" and Pr. 59 Remote function selection = "0". (all are initial values)
[RUN] is not lit ... Why?
Check that wiring is correct. Check it again.
Check for the Pr. 79 setting once again. (Pr. 79 must be set to "4"). (Refer to page 47)
Change the frequency of the terminal RL, RM, and RH.
Refer to page 64 to change the running frequency at each terminal in Pr. 4 Multi-speed setting (high speed), Pr. 5 Multi-speed
setting (middle speed), and Pr. 6 Multi-speed setting (low speed).
