(1) Input terminal function assignment
Using Pr. 178 to Pr. 182, set the functions of the input terminals.
Refer to the following table and set the parameters:
Setting Signal
Pr. 59 = 0 (initial value)
0 RL
Pr. 59 ≠ 0 ∗1
Pr. 59 = 0 (initial value)
1 RM
Pr. 59 ≠ 0 ∗1
Pr. 59 = 0 (initial value)
2 RH
Pr. 59 ≠ 0 ∗1
3 RT Second function selection
4 AU Terminal 4 input selection
5 JOG Jog operation selection
External thermal relay input ∗2
7 OH
8 REX 15-speed selection (combination with three speeds RL, RM, RH)
10 X10 Inverter run enable signal (FR-HC, FR-CV connection)
12 X12 PU operation external interlock
14 X14 PID control valid terminal
PU/External operation switchover (turning ON X16 selects External
16 X16
operation)
18 X18 V/F switchover (V/F control is performed when X18 is ON)
24 MRS Output stop
25 STOP Start self-holding selection
60 STF Forward rotation command (assigned to STF terminal (Pr. 178) only) —
61 STR Reverse rotation command (assigned to STR terminal (Pr. 179) only) —
62 RES Inverter reset
PU/NET operation switchover (turning ON X65 selects PU
65 X65
operation)
External/NET operation switchover (turning ON X66 selects NET
66 X66
operation)
Command source switchover (turning ON X67 makes Pr. 338 and Pr.
67 X67
339 commands valid)
9999 — No function
∗1 When Pr. 59 Remote function selection ≠ "0", the functions of the RL, RM and RH signals are changed as given in the table.
∗2
The OH signal turns ON when the relay contact "opens".
NOTE
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.
Same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
The priorities of the speed commands are in order of jog > multi-speed setting (RH, RM, RL, REX) > PID (X14).
When the X10 signal (FR-HC, FR-CV connection-inverter operation enable signal) is not set or when the PU operation
external interlock (X12) signal is not assigned with Pr.79 Operation mode selection set to "7", the MRS signal shares this
function.
Same signal is used to assign multi-speed (7 speeds) and remote setting. These cannot be set individually.
(Same signal is used since multi-speed (7 speeds) setting and remote setting are not used to set speed at the same
time.)
When V/F control is selected by V/F switchover (X18 signal), second function is also selected at the same time.
Control between V/F and General-purpose magnetic flux can not be switched during operation. In case control is
switched between V/F and General-purpose magnetic flux, only second function is selected.
Turning the AU signal ON makes terminal 2 (voltage input) invalid.
(2) Response time of each signal
The response time of the X10 signal and MRS signal is within 2ms.
The response time of other signals is within 20ms.
