10-1. Belt Speed [m/min]
This item shows the velocity of the belt. When either one of the three phase modes
(“NORMAL MODE A”, “NORMAL MODE B”, “NORMAL A SLOW”, “PHASE
MEASURE”, “ANA. NORMAL A”, or “ANA. A SLOW”) is selected in [SPEED
ENTRY SELECT], the belt velocity is calculated based on the pulse input from the
velocity detector. If the belt travels in reverse direction in PHASE MEASURE mode,
belt speed is displayed as “-0”.
If an ANA option is installed in the system, and “ANALOG 1CH MODE” or
“ANALOG 2CH MODE” is selected for the option, belt speed is calculated using the
analog input [%].
If “NONE” is selected, the value specified for [RATED BELT SPEED] is used as the
belt speed.
Decimal place for belt speed is fixed to 2 (e.g. 000.00).
The items which require setting differ depending on the use of the analog input.
