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 contact a. (You cannot set contact
b.)
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 contact a. (You cannot set
contact b.)
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
μ
s, 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).
Function
If the CONTROL mode Selection (Pn001) is set to 3 to 5, the CONTROL mode can be switched
as given in the following table.
Pn001 set value OFF (FIRST CONTROL mode) ON (SECOND CONTROL mode)
3 Position control Speed control
4 Position control Torque control
5 Speed control Torque control
