1.15 TORQUE BOOST

When this parameter has been activated, the voltage to the motor changes au-

tomatically with high load torque which makes the motor produce sufficient

torque to start and run at low frequencies. The voltage increase depends on

the motor type and power. Automatic torque boost can be used in applications

with high load torque, e.g. in conveyors.

0 = Disabled

1 = Enabled

Note: In high torque - low speed applications - it is likely that the motor will

overheat. If the motor has to run a prolonged time under these conditions,

special attention must be paid to cooling the motor. Use external cooling for

the motor if the temperature tends to rise too high.

Note: The best performance can be reached by running motor identification,

see par. 1.18.

1.16 SWITCHING FREQUENCY

Motor noise can be minimised using a high switching frequency. Increasing

the switching frequency reduces the capacity of the frequency converter unit.

Switching frequency for Vacon 10: 1.5…16 kHz.

1.17 BRAKE CHOPPER

Note! An internal brake chopper is installed in three phase supply MI2 and MI3

size drives.

0 = Disable (No brake chopper used)

1 = Enable: Always (Used in Run and Stop state)

2 = Enable: Run state (Brake chopper used in Run state)

When the frequency converter is decelerating the motor, the energy stored to the in-

ertia of the motor and the load are fed into an external brake resistor, if the brake

chopper has been activated. This enables the frequency converter to decelerate the

load with a torque equal to that of acceleration (provided that the correct brake re-

sistor has been selected). See separate Brake resistor installation manual.

1.18 MOTOR IDENTIFICATION

0 = Not active

1 = Standstill identification

When Standstill identification is selected, the drive will perform an ID-run

when it is started from selected control place. Drive has to be started within

20 seconds, otherwise identification is aborted.
