Use switches to give a frequency command (multi-speed setting)

POINT
Use
to give a start command.
Pr. 79 Operation mode selection must be set to "4" (External/PU combined operation mode 2).
The initial values of the terminals RH, RM, RL are 60Hz, 30Hz, and 10Hz. (Use Pr. 4, Pr. 5 and Pr. 6 (Refer to
page 63) to change.)
Operation at 7-speed can be performed by turning ON two (or three) terminals simultaneously.

When the frequency command is not given, [RUN]
flickers fast.
4.
Turn ON the low speed signal (RL).
The output frequency increases to 10Hz according
to Pr. 7 Acceleration time.
[RUN] display is lit during forward rotation operation
and flickers slowly during reverse rotation operation.
5.
Turn OFF the low speed signal (RL).
The output frequency decreases to 0Hz according to
Pr. 8 Deceleration time.
[RUN] flickers fast.
6.
Turn OFF
.
[RUN] turns OFF.
REMARKS
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 light ... 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 63 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).
