26
ALM+
Servo
alarm
output
Example: Pin 26 is connected to +24 V and Pin 27 to the
upper computer.
When the servo alarms, the upper computer is able to
receive the electrical level of +24V.
When the servo is in normal state, +24V is disconnected
from the upper computer.
Example: Pin 27 is connected to 0V and Pin 26 to the
upper computer.
When the servo is in no rmal state, the upper computer is
able to receive the electrical level of 0V.
When the servo alarms, 0V is disconnected from the
upper computer (normal close).
● Electrical level inversion or normal open/ normal
close switching can be done via Parameter PA57.

COIN+
The
second
reset ( used for
Siemens)
Positioning
done
or
speed
reached
Example: Pin 28 is connected to +24V and Pin 2 9 to the
upper computer.
When positioning is done, speed is reached, or in zero
position , the upper computer is able to receive the
electrical level of +24V; otherwise +24V is
disconnected from the upper computer.
Example: P in 29 is connected to 0V and Pin 28 to the
upp er computer.
When positioning is done, speed is reached, or in zero
position , the upper computer is able to receive the
electrical level of 0V; otherwise 0V is disconnected
from the upper computer.
● Electrical level inversion or normal open/ normal
close switching can be done via Parameter PA57.
● Primarily used for reset of Siemens 801 and 802
numeric controls in the mac hine tool industry.
