About us
Description
The PTO channel provides a pulse output signal at a specified frequency.
Physical Inputs/Output
Input/Output
Description
Drive_Ready&Emergency input (optional)
The pulse output is generated as long as a current goes through Drive_Ready&Emergency input.
Proximity&LimitSwitch input (optional)
Used as a LimitSwitch.
Drive_Enable output
To be connected to the corresponding input of the drive.
Enables the drive when active.
This output is directly controlled through an implicit command object (%Qr.m.c.0).

WARNING
UNINTENDED APPLICATION BEHAVIOR-COMMAND SENT ON EACH PLC CYCLE
Commands will be sent on every PLC cycle if EN is set to 1.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Command example using the WRITE_CMD command mechanism in ST representation: 
if (ChangeFreq = True) then  %CH0.1.0.CMD_CODE := 1;  %CH0.1.0.TGT_VELOCITY := 5000; WRITE_CMD(%CH0.1.0); ChangeFreq := False; end_if;
