Number of pulses is counted during this time
It can be adjusted from to
7.8 FREQUENCYMETER / TACHOMETER Parameters
i
Selection of Measurement Method
Frequency or cycle is calculated by measuring cycle time of the signals in Ch-
A input
Time Out (Input Signal Reset Time)
The actual value is reset, if there is no signal in Ch-A input during this time
It can be adjusted from to
Frequency or cycle is calculated by counting the pulses in Ch-A input during
the time is set in measurement period parameter
Output-1 Function
Output-1 is latched. It does not change position until manual reset is applied.
Non-latched with hysteresis output is selected.
Output-1 is an alarm output. For details, refer to Output-1 Alarm functions
parameter .
Measurement Period
For details on parameters, refer to Section 8 (Program Parameters).
SET1
SET value for Output-1. Control of the Output-1 is done
according to this value. It can be adjusted from to
SET value for Output-1. Control of the Output-1 is done
according to this value. It can be adjusted from to
SET2
SET value for Output-2. Control of the Output-2 is done
according to this value. It can be adjusted from to
Pulse Time of Ch-A, Ch-B, Reset and Pause Inputs
It is used to protect against the electrical contact debounce or the signal that
is less than the determined pulse time.
It can be adjusted from to msec . If it’s adjusted to
then there is no time protection for Ch-A and Ch-B. If the parameter
value is adjusted or then Reset and Pause protection
times are accepted as 2 msec.
