DRIVING THE MOTOR
[EXT] is not lit even when is pressed ... Why?
Switchover of the operation mode with is valid when Pr. 79 = "0" (initial value).
50Hz, 30Hz and 10Hz are not output from RH, RM and RL respectively 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 for the Pr. 79 setting once again. (Pr. 79 must be set to "0" or "2".) (Refer to page 62)
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)] is not lit. ... Why?
Check that wiring is correct. Check it again.
Check that "60" is set in Pr. 178 STF terminal function selection (or "61" is set in Pr. 179 STR terminal
function selection)?
(All are initial values.)
How is the frequency setting from 4 to 7 speed ?
In the initial setting, when two or more of multi-speed settings are simultaneously selected, priority is
given to the set frequency of the lower signal. For example, when RH and RM signals turn ON, the
RM signal (Pr. 5) has a higher priority. By setting Pr. 24 to Pr. 27 (multi-speed setting), up to 7- speed
can be set by combinations of RH, RM, and RL signals. Refer to the Chapter 4 of the Instruction
Manual (Applied).
Perform multi-speed operation more than 8 speed. ... How?
Use the REX signal to perform the operation. Maximum of 15-speed operation can be performed.
Refer to Chapter 4 of the Instruction Manual (Applied).
REMARKS
· External operation is fixed by setting "2" (External operation mode) in Pr. 79 Operation mode selection when you do not want to take
time pressing or when you want to use the current start command and frequency command. (Refer to page 62)
