9999 No function
*1 When Pr. 59 Remote function selection = "1 or 2", the functions of the RL, RM and RH signals change as listed above.
*2 The OH signal turns on when the relay contact "opens".
CAUTION
⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please
make setting after confirming the function of each terminal.
⋅ One function can be assigned to two or more terminals. In this case, the terminal inputs are ORed.
⋅ The priorities of the speed commands are in order of jog, multi-speed setting (RH, RM, RL, REX) and PID (X14).
⋅ When the X10 signal (FR-HC, MT-HC, FR-CV connection - inverter operation enable signal) is not set or when the PU
operation external interlock (X12) signal is not assigned at the Pr. 79 Operation mode selection setting of "7", the MRS signal
shares this function.
⋅ Use common terminals to assign multi-speeds (speed 7) and remote setting. They cannot be set individually.
(Common terminals are used since these functions are designed for speed setting and need not be set at the same time.)
(2) Response time of each signal
⋅ The response time of the X10 signal is within 2ms. However, when the X10 signal is not assigned at the Pr. 30
Regenerative function selection setting of "2" (FR-HC/MT-HC/FR-CV connection), the response time of the MRS
signal is within 2ms.
Pr. 17 MRS input selection is made invalid.
