The alarm-related parameters consist of the alarm type (type, stand-by action, energized/
de-energized, and latch function), PV velocity alarm time setpoint, alarm hysteresis,
alarm (On-/Off-) delay timer, and alarm setpoint.
Alarm-related parameter Number of settings
Alarm type 4 (number of settings)
PV velocity alarm time setpoint 4 (number of settings)
Alarm hysteresis 4 (number of settings)
Alarm (on-/off-) delay timer 4 (number of settings)
Alarm setpoint 4 (number of settings) x 4 (number of groups)
► Alarm hysteresis: 11.3 Setting Hysteresis to Alarm Operation
► Alarm delay timer: 11.4 Delaying Alarm Output (Alarm Delay Timer)
► Alarm setpoint: 6.5 Setting Alarm Setpoint
Factory default: Only four groups of alarm-related parameters are displayed.
