About us
Description
This function is used to generate a pulse output at a specified frequency, by reaching this frequency smoothly through an acceleration ramp.
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 LimitSwitch.
Drive_Enable output:
To be connected to the corresponding input of the drive.
Enables the drive when active.
This output is directly controlled by the user 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 (ChangeVel = True) then  %CH0.1.0.CMD_CODE := 2;  %CH0.1.0.TGT_VELOCITY := 5000; WRITE_CMD(%CH0.1.0); ChangeVel := False; end_if;
