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 Refer to page 99.
 Pr. 20 Acceleration/deceleration reference speed Refer to page 97.

Pr. 79 Operation mode selection Refer to page 164.

Pr. 178 to Pr. 182 (input terminal function selection) Refer to page 117.
 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).

Signal name 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.
