DC Motor Braking
When applying the brake in a servo motor, a generative process can occur
whereby the kinetic energy of the motor is converted into electrical energy.
The energy of the motor is thereby fed back into the supply of the servo
motor output stage; this then increases the supply voltage. It should be
noted that a regenerative voltage of 65 V at the motor supply connection is
not exceeded! The external capacity of the motor supply is may be needed.
If the capacitors in the power supply are insufficient, a regen resistor, which
converts the excess energy into heat must be connected to the servo motor
output stage. When selecting the power supply, it is important to ensure
that it is appropriately feedback-resistant up to the maximum regenerative
voltage that occurs.
Use wires only that are allowed for at least 75 °C!
There is no motor thermostat evaluation in the motor output stage.
Incorrectly set parameter or incorrect wiring can lead to destruction of the
motor. In particular, motor currents and the I2T settings (A-I2TT, A-I2TERR)
must be monitored, which can be parameterized in the DIAS-Drive Editor
via the LASAL Class 2 tool.
Only motors in a star connection can be used.
