Function
These two signals are the inputs to prohibit forward and reverse rotation (overtravel inputs).
If Drive Prohibition Input Selection (Pn504) is 1, you can use the setting of Stop Selection
(Pn505) to select the operation to be taken upon input of each prohibit signal.
If Drive Prohibition Input Selection (Pn504) is 2, drive prohibition input protection (E380)
actuates upon input of a drive prohibition.
Precautions for Correct Use
Both signals are disabled (in a state in which drive prohibition will not operate) in the default settings.
If prohibiting the drive input is required, set the Drive Prohibit Input Selection (Pn504) to either 0 or
2. The setting on the Input Signal Selection 1 to 10 (Pn400 to Pn409) can change the logic and
allocation for the respective Input terminals (CN1 to 8, 9 and 26 to 33).
Alarm Reset Input (RESET)
Pin 31: Alarm reset input (RESET)
This is the allocation at default setting. You can change the logics and allocations for input
terminals (CN1 to 8, 9 and 26 to 33) according to the settings of Input Signal Selection 1 to 10
(Pn400 to 409).
The input logic for the alarm reset input (RESET) is always NO. (You cannot set NC logic.)
Function
It is the external reset input for servo alarm. (A reset occurs at the rising edge of this input.)
Inputting for 120 ms or more releases an alarm condition.
An alarm reset also resets the content of the error counter, upon which the position loop
becomes no longer effective.
Eliminate the cause of the alarm before resuming operation. To prevent danger, turn OFF the
Operation command (RUN) first, then input the alarm reset signal.
Some alarms cannot be reset with this input.
Error Counter Reset Input (ECRST)
Pin 30: Error counter reset input (ECRST)
This is the allocation at default setting. You can change the functions for input terminals (CN1
to 8, 9 and 26 to 33) according to the settings of Input Signal Selection 1 to 10 (Pn400 to 409).
You can only allocate the error counter reset input (ECRST) to pin 30 (SI7). Allocating to any
other terminal generates an error counter reset signal allocation error (A332).
The input logic for the error counter reset input (ECRST) is always NO. (You cannot set NC
logic.)
Function
Inputting the error counter reset resets the content of the error counter, upon which the position
loop becomes no longer effective.
You can use Error Counter Reset Condition Selection (Pn517) to set the status (level) signal
(ON) or differential (rising edge) signal (from OFF to ON).
Input the differential signal for at least 100 μs, or status signal for at least 1 ms. A reset may
not occur if the time is shorter.
Control Mode Switching (TVSEL)
Pin 32: Control mode switching (TVSEL)
This is the allocation at default setting. You can change the logics and allocations for input
terminals (CN1 to 8, 9 and 26 to 33) according to the settings of Input Signal Selection 1 to 10
(Pn400 to 409).
