6. Inputs/Outputs

Please note that ACS 850 has 3 Programmable analog inputs, Two programmable analog outputs, Threeprogrammable relay outputs and seven programmable digital inputs.In addition to the above, for interfacing with the PLC/DCS, a host of Interface Modules are offered as anoption. We request you to let us know the protocol required for the same.

7.0 Power Loss Ride Through. If the incoming supply voltage is cut off, the ACS 850 will continue to operateby utilizing the kinetic energy of the rotating motor. The ACS 850 will be fully operational as long as themotor rotates and generates energy to the ACS 850.

8.0 Automatic StartThe Automatic Start feature of the ACS 850 outperforms the flying start and ramp start features normallyfound in frequency converters. Because ACS 850 can detect the state of the motor within a fewmilliseconds, starting is immediate under all conditions. There is no restart delay.

9.0 Flux OptimizationFlux Optimization of the ACS 850 reduces the total energy consumption and motor noise level when thedrive operates below the nominal load. The total efficiency (motor and the drive) can be improved by 1 %to 10 %, depending on the load torque and speed.

10.0 Critical Speed/Constant Speed Function

Critical Speeds :There is a Critical Speeds function available for applications where it is necessary to avoidcertain motor speeds or speed bands due to e.g. mechanical resonance problems.The ACS 850 makes it possible to set up five different speeds or speed bands which will be avoided duringoperation.Each critical speed setting allows the user to define a low and a high speed limit.If the speed reference signal requires the ACS 850 to operate within this speed range the Critical Speedsfunction will keep the ACS 850 operating at the low (or high) limit until the reference is out of the criticalspeed range. The motor is accelerated/decelerated through the critical speed band according to theacceleration or deceleration ramp.Constant Speeds : In the ACS 850 it is possible to predefine 15 constant speeds. Constant speeds areselected with digital inputs. Constant speed activation overrides the external speed reference.

11.0 Accurate Speed/Torque Control

Accurate Speed Control : The static speed control error is typically + 0.1% to + 0.5 % of motor nominalspeed, which satisfies most industrial applications. If even more precise speed regulation is required, apulse encoder can be connected. With a pulse encoder, the static speed control error is typically 0.01% ofmotor nominal speed.


7/16




The dynamic speed control error is typically + 0.4 %sec. at 100 % load torque step without a pulseencoder or tachogenerator. With a pulse encoder, dynamic speed control error is typically + 0.1 %sec.

Accurate Torque Control : The ACS 850 can perform precise torque control without any speed feedbackfrom the motor shaft. With torque rise time less than 5 ms at 100 % torque reference step compared toover 100 milliseconds in frequency converters using sensorless flux vector control, the ACS 850 isunbeatable.By applying a torque reference instead of a speed reference, the ACS 850 will maintain a specific motortorque value; the speed will adjust automatically to maintain the required torque.

12.0 DC Magnetizing

When DC Magnetizing is activated the ACS 850 automatically magnetises the motor before the start. Thisfeature guarantees the highest possible breakaway torque, even 200 % of motor nominal torque. Byadjusting the premagnetising time, it is possible to fix the motor start with a mechanical brake release, forexample. The Automatic Start feature and DC Magnetizing cannot be activated at the same time.

13.0 Speed Controller Tuning

During the motor identification run the ACS 850 speed controller is automatically tuned. However, it ispossible to manually adjust the controller gain, integration time and derivation time, or let the ACS 850perform a separate speed controller Autotune Run. In Autotune Run, the motor is driven through a seriesof movements and the speed controller is tuned based on the load and inertia of the motor and themachine.

14.0 Fault Diagnostic

The Fault History contains information on five most recent faults detected by the the ACS 850. Faults aredisplayed in words along with the elapsed time of the fault from the commissioning.


8/16




14 . DC hold

By activating the motor DC hold feature it is possible to lock the rotor at zero speed. When both thereference and the motor speed fall below the preset DC hold speed, the drive stops the motor and starts toinject DC into the motor. When the reference speed again exceeds the DC hold speed , the normal driveoperation resumes.

15.0 CONSTRUCTION DETAILS OF PANELS

15.1 Please note that all the panels shall be Free Standing, Floor Mounted, Dead Rear type. All the loadbearing members shall be 2.0mm thickness sheet steel and all non-load bearing members shall be 1.6 mmthickness. All the panels shall be dust and vermin proof with IP42 protection.
