Speed setting by external terminals
4.7.3
Remote setting function (Pr. 59)
The above parameter can be set when
Pr. 160 Extended function display selection
=
"0"
. (Refer to page 156.)
When
Pr. 59
≠
"0" (remote setting enabled), the functions of the signals are as shown in the following table.
NOTE
The
Pr. 15
setting should be equal to or higher than the
Pr. 13 Starting speed.
Changing the terminal assignment using
Pr. 178 to Pr. 182 (input terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
During Jog operation, the second acceleration/deceleration via the RT signal cannot be selected. (The other second
functions are valid.
(Refer to page 227.)
)
When
Pr. 79
Operation mode selection
= "4", pressing
of the operation panel and
/
of the parameter unit
(FR-PU07) starts the drive unit and pressing
stops the drive unit.
This function is invalid when
Pr. 79
= "3".
Parameters referred to
Pr. 13 Starting speed
Pr. 20 Acceleration/deceleration reference speed
Pr. 79 Operation mode selection
Pr. 178 to Pr. 182 (input terminal function selection)
Even if the operation panel is located away from the enclosure, you can use contact signals to perform continuous
variable-speed operation, without using analog signals.
By merely setting this parameter, you can use the acceleration, deceleration and setting clear functions of the
motorized speed setter (FR-FK).

Operation status
Description
STF/STR
Forward/reverse
The drive unit accelerates the motor in forward or reverse directions up to the main speed
or to the set speed stored by the remote setting function.
RH
Acceleration
The set speed increases according to the time set in
Pr. 44
.
RM
Deceleration
The set speed decreases according to the time set in
Pr. 45
.
RL
Clear
The set speed is cleared and the main speed is applied.
Terminal 2 (analog
signal)
Main speed
Set the main speed as a base, and increase it with the RH signal and decrease it with the
RM signal.
