System parameters
Parameter Description, values, default value
FOx
Function Output (switching function of the outputs 1/2)
F1
The relay is de-energised in case of slip and during the start-up delay STP.
(+ signal on terminal 17 = relay energised)
F2
The relay is energised in case of slip and during the start-up delay STP.
(+ signal on terminal 17 = relay de-energised)
F3
The relay is de-energised in case of synchronous running and during the start-up delay STP.
(+ signal on terminal 17 = relay de-energised)
F4
The relay is energised if the number of differential pulses < SPx and during STP.
Relay de-energises if the number of differential pulses = SPx.
(+ signal on terminal 17 = both relays energised)
Switching function of the outputs:
- relay 1 de-energises if input 1 counts more pulses than input 2,
i.e. if the pulse sequence on input 2 becomes "slower" and the number of differential
pulses SP 1 is reached. Display: 1 > 2
- relay 2 de-energises if input 2 counts more pulses than input 1,
i.e. if the pulse sequence on input 1 becomes "slower" and the number of differential
pulses SP 2 is reached. Display: 2 > 1
• Values: 1...4
• Default value: 4 (recommended setting for synchronous monitoring!)
NCx
Number of Cams (number of switching cams)
Allows the indication of the rotational speed in RPM if there is more than one switching
cam per revolution.
It is also possible to compensate for a different number of cams of the spindles or shafts.
• Values: 1...999
• Default value: 1 (most sensitive setting and setting with the fastest reaction with the
same number of cams; displayed value shows pulses/min. instead of RPM or Hz.)
STP
Start-up Delay Time Parallel (start-up delay outputs 1/2)
Normally the output relays are energised after power on of the monitor until the drive is
switched on.
The outputs then switch depending on the switching function and state of the plant.
The parameter applies to both outputs. It can be used to compensate for a slipping start
of the plant until synchronous running is achieved.
Monitoring starts on the first pulse edge after this time has elapsed.
The start-up delay can also be released externally while the monitor remains connected
(see "Electrical connection").
• Values: 0.0...1000.0 s
• Default value: 0.0
FWx
Function Wire Break (wire monitoring, only FS-3N)
Relay action in case of a wire fault
if
FOx = 1
FOx = 2/3
FOx = 4
(default value)
• Values: 0 = inactive / 1 = active
• Default value: 0
FWx = inactive (0)
relay remains energised
relay remains de-energised
relay remains energised
MONITOR
FWx = active (1)
