Feedrate
The following settings are available for Feedrate limits:
High Feedrate ↑
Low Feedrate
High Feedrate Delay
Low Feedrate Delay
High Abs Deviation
Low Abs Deviation
High Rel Deviation
Low Rel Deviation
High Deviation Delay
Low Deviation Delay ↓
High Feedrate
If the actual feedrate exceeds this limit for duration longer than the High
Feedrate Delay value (see below) then the logical output “High Feedrate” is set.
Note that this setting is independent of setpoint, and will activate anytime the
limit is exceeded, even if the intended rate is higher than the limit. The High
Feedrate and Low Feedrate limits are usually used with Belt Weighers or Belt
Scales where there is no closed loop control over feedrate. This limit is set in
units of feedrate.
Low Feedrate
If the actual feedrate drops below this limit for duration longer than the Low
Feedrate Delay value (see below) then the logical output “Low Feedrate” is set.
This limit is set in units of feedrate.
Note this limit is only active under the following conditions:
• Feeder Control is enabled (see Main Menu > Advanced Setup >
Configuration > Feeder Control) and the belt is commanded to run.
• Feeder control is not enabled and the logical input “Belt Running” is on.
• No calibration routine is running.
High Feedrate Delay
This value provides a delay for the High Feedrate limit, in order to prevent
nuisance alarms. The feedrate must remain above the limit value for duration
