Stepper Motor Braking
When applying the brake in a stepper motor, a generative process can occur where-
by 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 stepper 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 insuffi-
cient, a regen resistor, which converts the excess energy into heat must be connect-
ed to the stepper motor output stage. When selecting the power supply, it is im-
portant to ensure that it is appropriately feedback-resistant up to the maximum re-
generative voltage that occurs.
The connector at X2 cannot be inserted or removed during operation!
Note on S-DIAS Supply
If this S-DIAS module is connected to an S-DIAS supply module with several S-DIAS
modules, the total current of the modules used must be determined and checked.
The total current of the +24 V supply cannot exceed 1.6 A!
The total current of the +5 V supply cannot exceed 1.6 A!
The specification for the current can be found in the module-specific technical doc-
umentation under "Electrical Requirements".
Si ce module S-DIAS est conne
cté à un module d’alimentation S-DIAS suivi de
plusieurs modules S-DIAS, le courant total des modules utilisés doit être déterminé
et vérifié.
Le courant total de l'alimen24 V ne peut pas dépasser 1,6 A!
Le courant total de l'alimen5 V ne peut pas dépasser 1,6 A!
Le cahier des charges pour le courant peut être trouvé dans la documentation
spécifique au module sous "Spécifications électriques".
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.
