Use switches to give a start command and a frequency command (multi-speed
setting)
[Connection diagram]
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.
(Refer to page 89 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.
(Refer to chapter 4 of
the instruction manual (applied).)
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 60.)
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 62.)
Change the frequency of the terminal RL, RM, and RH. ... How?
Refer to
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)
.
