9 Standard Input Functions
The ATD 50 Actuator
®
can accept either momentary or maintained contacts. The factory
default is momentary. If additional safety requirements are desired, you can specify
MAINTAINED CONTACT for the input signals. Maintained Contact Signals can be
programmed in the Basic Functions Menu in the SERsoft programming software.
If you desire to use maintained contacts for input signals, we suggest using the
following logic in your PLC or CNC:
The error signals for All Errors (General Error 1 - Relay 1 - E1 to E2) and
General Errors (General Error 2 - Relay 4 - E7 to E8) are activated during
calibration runs. The maintained contact can be held until the errors clear. In
this situation, the machine controller can monitor Relay 1 or 2 and maintain
the inputs to A2 and A7 until the errors clear.
