The time constant for pulse input filtering T f shall meet: T f ≤(20%~25%) Tmin If the maximum frequency of the input pulse signal (or minimum pulse width) is known, the recommended filtering time parameter is shown in the following table: Parameter functions: Select which external DI signal is used to clear deviation. P1-16 = 0 : Clear through P-CLR rising edge P1-16 = 1 : Clear through P-CLR low level P1-16 = 2 : Clear through P-CLR high level P1-16 = 3 : Clear through P-CLR falling edge Parameter functions: Set the warning threshold for the position following deviation.
When the position deviation reaches or goes beyond the set value, warning signal for too high position following deviation will be output. The motor continues running, the LED monitor displays AlE05, and output of the DO terminal defined as WARN is valid. Once the position deviation falls below the set value, the warning will be automatically cancelled. Parameter functions: Set the alarm threshold for the position following deviation. When the position deviation reaches or goes beyond corresponding set value, alarm signal for too high position following deviation will be output.
