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
Pr. 59 = 0 (initial value)
1
RM
Pr. 59  0
Pr. 59 = 0 (initial value)
2
RH
Pr. 59  0
3
RT
Second function selection
4
AU
Terminal 4 input selection
5
JOG
Jog operation selection
7
OH
External thermal relay input
8
REX
15-speed selection (combination with three speeds RL, RM, RH)
10
X10
Inverter run enable signal (FR-HC2, 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)
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
64
X64
Starting frequency for elevator mode
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)
72
X72
PWM frequency selection
9999
No function

When Pr. 59 Remote function selection  "0", the functions of the RL, RM and RH signals are changed as given in the table.

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-HC2, 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.)
 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.
