ACS550 Drive
ACS550 Drive1. Input voltage range of VFD is 3 Phase 208 240V,
380 480V, 500 600V. With +10/-15% tolerance.2. Input frequency to
the VFD is 48 60Hz.3. Output power range is. 0.75 100Hp(208 240V),
1 550Hp(380 480V), 1.5 150Hp(500 600V)4. Input displacement power
factor cos is 98% at nominal load.5. The VFD can provide full rated
output current continuously, 110% of rated current for 1min every
10 min,
For heavy duty use it can supply continuous heavy duty base
current with 150% overload for 1min every 10min,180% heavy duty
base current available for 2 sec every one min.
6. The control principle used is sensor less vector control,
with advance IGBT power switching technology.7. The VFD is capable
of working in the ambient temperature range of -15C to 50C
throughout the day
With current Deration of 1% per C above 40C. Relative humidity
should be less than 95% without
Condensation. The VFD can provide rated current at 0 1000 meter
altitude reduced by 1% per 100m Over 1000m to 2000m.
8. The VFD is available with IP21 protection as standard and
IP54 as option.
9. The VFD is provided with inbuilt EMC(RFI) filter category C2(
1st environment) i.e. industrial low voltageNetwork. For motor
cable longer than 100m external RFI filter is required10. For
harmonic suppression the VFD is provided with swinging DC choke,
which changes inductance
According to load. This is ABBs patented and it reduces total
harmonic distortion by up to 25% lessThan the permissible
value.
11. Brake chopper is built in up to 15Hp (480 and 600V) and up
to 10Hp (240V). Brake chopper is provided
as standard in frame size R1 and R2, above this it is
optional.
12. The VFD can be wall mounted from frame size R1 R6(0.75
150Hp), and free standing for frame size
R7 & R8(150 550Hp).
13. The VFD has two user-selectable acceleration and
deceleration ramp. It is possible to
adjustAcceleration/deceleration time (0 1800S) and select the ramp
shape. Switching between the two ramps
Can be controlled via a digital input.
14. The VFD have four selectable switching frequencies 1KHz,
4KHz, 8KHz & 12KHz for 0.75 to 150Hp
And 1 KHz, 4 KHz above that. Default is 4 KHz.
15. The VFD has the motor speed control static speed accuracy of
20% motor nominal slip. And dynamic
Accuracy greater than 1% sec with 100% torque step. Torque step
rise time is greater than 10ms with
Nominal torque and non linearity is 5% with nominal torque.
16. The VFD provides the following fieldbus communication.
Profibus DP, DevicNet, ControlNet, EtherNet/IP,
Modbus/TCP(Embedded), CANopen.
Serial communication via RS485. ACH550 supports BACnet/ N2/ FLN
apart from the other communication methods mentioned here.17. The
input/output options available are
2 Programmable analog input: 0 10V Rin >312k single ended
0 - 20 mA. Rin=100
