OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User’s Manual
Pin 30: Error Counter Reset Input (ECRST)
This is the default allocation. The function allocated to the input terminals (CN1 pin 1 to 8, 9, 26 to 33)
can be changed using Input Signal Selection 1 to 10 (Pn400 to Pn409).
The Error Counter Reset Input (ECRST) must be allocated only to pin 30 (SI7). Otherwise, a Error
Counter Reset Allocation Error (A332) will occur.
The input logic for the Error Counter Reset Input (ECRST) is NO contact only. (NC contact cannot be
set.)
Function
The error counter content will be reset when the Error Counter Reset Input signal turns ON, which
disables the position loop.
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).
The duration of differential signal input must be 100 µs or longer; the duration of status signal input
must be 1 ms or longer. The counter may not be reset if the signal is shorter than this duration.
Pin 32: Control Mode Switching (TVSEL)
This is the default allocation. The logic and allocation of input terminals (CN1 pin 1 to 8, 9, 26 to 33) can
be changed using Input Signal Selection 1 to 10 (Pn400 to Pn409).
Function
When Control Mode Selection (Pn001) is set to 3, this signal enables the control mode to be
switched as follows.
Pin 27: Gain Switching (GSEL)
This is the default allocation. The logic and allocation of input terminals (CN1 pin 1 to 8, 9, 26 to 33) can
be changed using Input Signal Selection 1 to 10 (Pn400 to Pn409).
Function
This signal is enabled when Gain Switching Mode (Pn115 for position control and Pn120 for speed
control) is set to 2.
When the signal is OFF, Gain 1 is enabled. When the signal is ON, Gain 2 is enabled.
