Use switches to give a start command and a frequency command (multi-speed
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. (Refer to page 79 to change frequencies
using Pr. 4, Pr. 5 and Pr. 6.)
· Operation at 7-speed can be performed by turning on two (or three) terminals simultaneously.
Instruction Manual (applied).)
AC power supply
Screen at powering on
The monitor display appears.
Change the Pr. 79 setting to "
(Refer to page 43 for change of the setting.)
Press the start switch
FWD (or REV) flickers.
When the frequency command is not
given, it flickers.
Turn on the low speed switch (RL).
The output frequency increases to 10Hz
according to Pr. 7 Acceleration time.
Turn off the low speed switch (RL).
The output frequency decreases to 0Hz
according to Pr. 8 Deceleration time.
Turn off the start switch
FWD (or REV) turns off.
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 52.)
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)
[FWD (or REV)] lamp is not lit ... Why?
Check that wiring is correct. Check the wiring once again.
Check for the Pr. 79 setting once again. (Pr. 79 must be set to "4".)
(Refer to page 54.)
Change the frequency of the terminal RL, RM, and RH. ... How?
Refer to page 79 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).
