Supported safety monitoring functions
The F-TM Count module provides safety monitoring functions that may be used to monitor
speed, position, and/or direction. These safety monitoring functions can be optionally
enabled to report safety events if configured safety limits are exceeded. The safety
monitoring functions include the following:
• Safe Direction (SDI) is used to monitor the direction of motion.
• Safety Limited Speed (SLS) is used to monitor that the motion does not exceed a preset
speed limit.
• Safe Operating Stop (SOS) is used to monitor for unintentional movement.
The F-TM Count module cannot take action that affects the safety functions.
The F-TM Count module reports when the parameter limits are exceeded to the F-CPU.
You must ensure code in your safety program does the following:
• Examines the safety-monitoring event data from the module
• Takes the necessary action to result in the appropriate outcome (for example, slowing
down, or shutting down movement)
2.2.2 Detection of counting signals
The F-TM Count module monitors the encoder signals and evaluates them as quadrature
encoded signals. The count direction is determined by the phase relationship of the encoder
signals.
You can specify the counter characteristics using the functions described below.
Counting limits
You can configure the behavior of the counter at the counting limits. The counting limits
define the counter value range used.
Start value
You can configure a start value within the counting limits.
