Max Rate Setpoint
This is the maximum allowed setpoint, and the logical output “High Setpoint” will
be set if it is exceeded for longer than the duration set by the limit “Max Rate
SP Delay” (see below). This limit is set in units of feedrate.
Note also that if setpoint clamping is enabled (see Main Menu > Advanced
Setup > Feeder Control > Settings), the setpoint used by the controller will be
clamped to this limit value even if it exceeded. However, in this case the logical
output “High Setpoint” will still be set.
Min Rate Setpoint
This is the minimum allowed setpoint, and the logical output “Low Setpoint” will
be set if the setpoint drops below this limit for longer than the duration set by
the limit “Min Rate SP Delay” (see below). This limit is set in units of feedrate.
Note also that if setpoint clamping is enabled (see Main Menu > Advanced
Setup > Feeder Control > Settings), the setpoint used by the controller will be
clamped to this limit value even if it drops below. However, in this case the
logical output “Low Setpoint” will still be set.
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.
Note that the Max and Min Rate Setpoint limits are active only if the Feeder
Control Method is set to “Rate Control” (see Main Menu > Advanced Setup >
Feeder Control > Method)
