Function assignment of external terminal and control
(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.
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.)
⋅
When V/F switching (X18) signal and load pattern selection forward rotation reverse rotation boost (X17) signal are not
assigned, the RT signal shares this function. (
Pr. 81 Number of motor poles = "12, 14, 16, 18, 20")
In this case, V/F control is controlled by the second function.
