Precautions For Using The Parameter Unit - Mitsubishi Electric Freqrol-A100 Instruction Manual

1.4.2
Precautions for Using the Parameter Unit
When using the PU, note the following points to make proper settings and enter correct values.
lnstructions for operation performed from the PU
Operation from the PU is only valid when the [PU OP]
key is pressed with
"On
(factory setting) set in parameter
79 or when PU operation or combined operation is se-
lected in Pr. 79.
In the monitoring mode, the running frequency cannot be
set by direct setting (by entering the frequency directly
from the key pad). To set the running frequency, either
perform step setting (change the frequency sequentially
by pressing the [A]/[V] key) and press the [WRITE] key,
or press the [PU OP] key after exiting from the monitoring
m ode.

lnstructions for monitoring
When the motor is to be run in the PU operation mode,
setting the running frequency and then pressing the start
key [FWD] or [REV] automatically switches the inverter
to the monitoring mode.
lnstructions for the operation modes
If the [PU OP] (or [EXT OP]) key is pressed, the mode
cannot be switched when:
(1) The motor is running;
(2) The external operation start signal (across terminals
STF or STR and SD) is on; or
(3) The set value of the operation mode select parame-
ter (Pr. 79) is any of 1 to 5 and 7.
When "0" is in the operation mode select parameter (Pr.
79), switching the inverter power off, then on or resetting
the inverter switches it to the external operation mode.

lnstructionsfor the number of digits and decimal point
of an input value
An input value of up to five digits may be entered. If the
value entered is in more than five digits, the most signifi-
cant digit is ignored.
(Entered) Ignored
Jog operation cannot be performed when:
(1) The motor is running; or
(2) The jog frequency (Pr. 15) is less than the starting
frequency (Pr. 13).
