Feature

Comment

Connection macros and application macros

Sets groups of parameters to simplify commissioning

• Connection macros for connections
• Application macros for application

Keep running mode

Single-parameter setting for a mode which keeps the motor going – enables V_DC max controller, kinetic buffering, restart after fault, flying start, disables warnings etc.

ECO mode

Economy mode – searches for most efficient operating point

Hibernation mode

Converter shuts down automatically when “nothing to do” but starts up again automatically when there is “something to do”.

PID controller

Integrated PID controller with auto-tuning function

Kinetic buffering (V_dcmin controller)

Keep the minimal DC voltage by the regeneration energy to keep running

V_dcmax controller

Auto change the ramp down time / decelerate time

I_max controller

Auto change the ramp up time to avoid the over-current

Automatic restart

Automatically restart the drive automatically once the power has been restored following a power failure. All faults are acknowledged automatically and the drive is switched on again.

Flying restart

Allows the converter to be switched to a rotating motor.

Energy consumption monitoring

Display simple estimate of “energy or cost saved” against use of a mains connected motor

50/60 Hz customization

Easy selection of 50 Hz (Europe, China) / 60 Hz (USA) operation

V/f and V²/f

V/f control is perfectly suitable for almost any application in which the speed of induction motors is to be changed. V²/fis suitable for centrifugal fans/pumps.

FCC

Maintains motor flux current for improved efficiency

Programmable V/fcoordinates

Freely adjust the V/f characteristics, e.g. torque behavior of the synchronous motor

JOG

Move the motor to test the direction or move the load to specific position. If the BOP switches to the JOG mode, the pressing of the start button of the BOP will run the motor to the JOG frequency. The releasing the start button will stop the motor.

DC braking

Stop the motor which runs at the constant speed and only is broken down to standstill in longer time intervals, e.g. centrifuges, saws, grinding machines and conveyor belts.

Mechanical hold braking control

The motor holding brake prevents the motor from undesirable turning when the converter is switched off. The converter has internal logic to control a motor holding brake.

USS

Universal Serial Interface Protocol

Modbus RTU

Modbus RTU communication available of the RS485

Super torque mode

Big torque boost for starting high-inertia applications

Hammer start mode

A number of torque pulses at start to start difficult or “stuck” loads

Blockage clearing mode

Multiple-reverse function to clear blocked pumps

Simple parameter-d menu on internal and external BOPs

Easy selection for displaying values, editing parameters, doing converter setup

Simple text menu for setup

The parameter number will be shown as the short text in 7-segment LED display.

Motor frequency display scaling

User settable display scaling for special applications i.e. rather than show Hz, it shows application-specific value like “gallons per minute”, “potatoes per hour”, etc.

Customization of parameter defaults

Customer or OEM can set his own special “unerasable” defaults (can be erased in a special mode)

Converter status at fault

Record the fault with running data

• Fault code
• Drive setpoint
• Drive status
• DC voltage
• Output current
• Output voltage

List of modified parameters

The parameter list only displays the parameters which were modified by users after this filter has been activated.

Belt-failure detection

Detect the load torque to avoid the failure between the mechanical connection between the motor, overload, locking or no-load operation.

Phase loss detection

Detect and protect against phase loss

Cavitation protection

Protection from cavitation damage to pumps

Condensation protection

Automatically apply DC current to motor to protect from condensation

Frost protection

Automatically turns motor to stop fluids freezing when temperature falls near or below freezing.

Motor staging

Automatic control and staging of several motors

Dual ramp

Switchable ramps for certain applications

Programmable fixed frequency setpoint

16 fixed frequencies can be defined and be switched by the digital inputs or the communication.

Drive data sets (DDS)

3 parameter sets for the motor and load, The user can switch the parameter set to fit the motors and applications.

Command data sets (CDS)

3 parameter sets for the setpoint and command. The user can switch the parameter set to fit the control system.

Flexible boost control

Increase the output voltage to compensate resistive losses or increase the output torque.

Skippable frequency bandwidth

Define 1 to 4 frequencies, which avoid effects of mechanical resonance and suppress frequencies within adjustable skip frequency bandwidth.

2-wire / 3-wire control

The wide range of setting options is especially intended to be able to emulate existing control methods on the plant or system side if the converter has to be integrated into an existing application.
