A38 Braking unit: Usage ratio 0.0 - 100 % FD: 1.5
The mentioned types of the ELVOvert SX series are equipped with a built in braking unit and a
braking resistor (80
Ω
; 120 W). The usage ratio should not exceed 1.5% if the internal
braking resistor is used.
At the usage of an external braking resistor (minimum
70
Ω)
in connection with the built in braking unit the
usage ratio can be increased according to the power
dissipation of the resistor.
The usage ratio of the built in braking unit with
reference to 100 sec can be adjusted in the range
of 0% to 100%. If this usage ratio is exceeded the braking unit is switched off and the inverter trips.
At the usage of an external braking unit the input value has to be set to 0.0 and the internal and also the
external braking resistors of the built in braking unit have to be disconnected.
Remarks: Remarks:
m
This parameter is only used at the ELVOvert SX 5.5 kW and 7.5 kW. In case of the inverter types
11 kW and 15 kW this parameter is set to 0.0 %.
m
The frequency inverters ELVOvert SX 400/11C15P and 15C22P do not have a built in braking unit.
A39 Signal „Frequency arrival“ 0.0 - A63 Hz FD: 0.0
On level
A40 Signal „Frequency arrival“ 0.0 - A63 Hz FD: 0.0
Off level
Via the parameter A49 the characteristic of the “Frequency arrival“-signal can be programmed. The relevant
frequencies (for the settings 1 and 2 at A49 ) are put in by the parameters A39 and A40 .
Remarks: Remarks:
m
The frequency can be adjusted in 0.1 Hz steps up to 100 Hz, above in 1 Hz steps.
m
Frequencies > 120 Hz are only possible if A64 is set to 400 Hz.
A44 Analogue output f/I/T 0 - 3 FD: 0
The terminal FM can be programmed to display different operating data.
0 Output frequency, analogue 0...10 V (10 V at arrival at the maximum voltage frequency)
1 Output current, analogue 0...10 V (10 V at 200 % of nominal current)
2 Torque, analogue 0...10 V (use only with SVC; with V/f only an estimated value with an accuracy of
+/- 20 % is available). (10 V at 200% of the nominal torque).
3 Output frequency as pulse signal
A47 Calculation factor n 0.0 - 99.9 FD: 1.0
Adjustment of a factor for calculating the drive speed d3.
A48 Frequency ref. selection 0 / 1 FD: 1
Program the set value input (terminal 0 - L ) for 0...5 V (input 0) or 0...10 V (input 1).
If the set value is adjusted by the use of a potentiometer and the internal reference voltage (terminal H - L, 10 V)
the set value input has to be put to 10 V.
Remark: Remark:
The switching of the set value definition to 4...20 mA is by a digital control input according to the
“MANUAL/AUTOMATIC“ switching (Control input 2 = 16 “Automatic-set value“).
