The following options are available
Measures
Advantages
Disadvantages
Switching off the load supply voltage
Direct de-energisation of the
motor
Uncontrolled coasting of the
motor
Switching off
control signals “STEP“ and “DIR“
Generation of a braking torque
by emitting a holding current
No voltage-free status of the
motor
Switching off the enable signal "EN"
Direct de-energisation of the
motor
Uncontrolled coasting of the
motor.
Motor could remain energised
in a fault condition.
Switching off the control signals at "STEP" and "DIR"
and delayed switching off of the enable signal "EN"
Generation of a braking torque
by output of the holding current
No direct de-energisation of the
motor.
Motor could remain energised
in a fault condition.
Switching off the control signals at "STEP" and "DIR"
and delayed switching off of the load supply voltage
Generation of a braking torque
by emitting a holding current
with subsequent de-
energisation of the motor
No direct de-energisation of the
motor.
