Note: ATV61 has only 8 preset speeds


ATV71 FUNCTIONSSpeed control

The ATV71 includes several motor control laws.

These different laws allow the drive to be adapted to a great variety of induction motors and machines.

SVC-U Voltage Sensorless Vector Control SVC-I Current Sensorless Vector Control* FVC Flux Vector Control (closed loop)* U/F Volt/Hertz SYN Synchronous motor (open loop)

(*) specific to ATV71



SVC-U

Voltage vector control is a compromise between performance and robustness.It functions only in open loop

Applications: Hoisting General material-handling equipment Machines requiring low speed torque Motors in parallel Unbalanced loads with the ENA function

Performances: Good dynamic characteristics Overtorque from 170% to more than 200%, depending upon the motor and the optimization of the settings (current limit adjustable from 150% to 165% In of the drive)

Nominal torque down to 1Hz (0.5Hz with optimization) in motor quadrant Nominal torque at slipping frequency in generator quadrant



SVC-U

Performances (cont’d): Maximum frequency of 500Hz Speed precision <=10 % of nominal slip Speed range 50 in motor quadrant (100 with optimization), depending on the slipping in generator quadrant It can be used with motors in parallel Band pass: 0.37 to 2.2kW 15 Hz 3 to 7.5kW 12 Hz 7.5 to 75kW 10 Hz 280 kW 4 Hz 500 kW 2 Hz

These performances are guaranteed for a motor of the same size than the drive and up to one size below.

The input of the nameplate and the autotune are necessary to obtain the optimum performances.



SVC-U



SVC-U


ATV71 FUNCTIONSSpeed controlSVC-I & FVC

The current vector control law allows the drive to attain better static and dynamic performance for torque and speedRequires a good understanding of the motor characteristicsIt functions in open (SVC-I) or closed loop (FVC)

Applications: Vertical hoisting movements High process rate machines Rapid material-handling Positioning Base law for the torque control function

Performances: Very good dynamic speed and torque characteristics Overtorque from 170% to more than 200% (depending on motor) Maximum frequency 500Hz The motor nameplate information and TUN are required. Flux feedback permits the improvement of braking performance without a braking resistor



Performance in open loop (SVC-I) The general performance is comparable to voltage vector control with better torque precision and better fluxed braking Can be used with motors in parallel if the motors are identical Nominal torque down to 1Hz (0.5hz with optimization) in motor quadrant Nominal torque at slipping frequency in generator quadrant Speed precision <=10 % of nominal slip Speed range 50 in motor quadrant (100 with optimization), depending on the slipping in generator quadrant Torque control mode: Precision 15% Up to +/-300% of nominal torque (Tn)









Performance in closed loop (FVC)

Torque at 0 speed is available in motoring or generating quadrant Speed precision is 0.02% of the nominal speed Speed range 1000 Band pass:

0.37 to 2.2kW 50 Hz3 to 7.5kW 30 Hz7.5 to 75kW 15 Hz280 kW 8 Hz 500 kW 5 Hz

Cannot be used with motors in parallel

Torque regulation mode: Precision 5% Up to +/-300% of nominal torque (Tn)









U/F

Volts/Hertz law is simple and robust, doesn’t contain speed loop, slip and IR compensation 2 profiles possible: U/F 2 points and U/F 5 points

Applications: Convenient for applications requiring low dynamic performance or low torque at low speed Typically: - special or unknown motors - high speed motors - motors in parallel (different sizes) - variable number of motors, switched on the fly - single phase motors - motors powered through a transformer - tests on small motors

U/F

Performance:

The voltage at the origin and the V/Hz profile are adjustable Maximum frequency of 1600Hz (up to 37kW) Speed precision = nominal slip Nominal torque starting from 5Hz A solution for testing equipment with reduced performance. Possible to control motors 10 times smaller than nominal power

ATV71 FUNCTIONSTorque control







A speed range around the reference is adjustable (DBP, DBN).Between these limits the drive is commanded in torque control If a level is attained, the drive limits the speed


ATV71 FUNCTIONSCurrent / Torque limitation

The levels of current limit are adjustable CLI current limit CLI2 2nd current limit (activated by CLF=LIx)

SSB allows specific actions to occur in case of limitation (current or torque)

no -> no detection alarm -> display + output assigned to STA fault -> limitation fault SSF

ST0 sets the current or torque limit time (before the action specified by SSB)

By default CLI is set to 150% In drive,it is possible to increase it up to 165%





The torque limit levels are adjustable (+/-300%) TLIM limitation of motoring torque TLIG limitation of generating torque TAI= AIx limitation of torque by analog input
