Function assignment of external terminal and control
(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
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 Drive unit 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)
23 LX Pre-excitation
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 Drive unit reset
64 X64 PID forward/reverse action switchover
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 PID integral value reset
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-drive unit 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.
