(4) Control during the servo OFF command
When a servo OFF command is input by an NC sequence input, the motor brake turns ON simultaneously when the
motor ON is shut off. Note that the vertical axis drop prevention control is not validated, so a drop due to the brake
operation lag occurs. When the servo OFF is canceled, a drop due to an uncontrolled state does not occur.
(5) Operation sequences when an emergency stop occurs
The motor brake control output operation when an emergency stop occurs differs according to the motor
deceleration stop method. Refer to section "Setting for emergency stop" for details on the operation sequences for
each stop method.
POINT
Using the high-speed ready ON sequence, set the parameter for all the axes including the spindle. Especially when it is not
set for the power supply control axis, power supply will not work at high-speed sequence.
CAUTION
When SV017/bit2=1, SP017/bit2=1 is set, for the model using an external dynamic brake, the Ready completion will be
delayed by 10ms to ensure the external contactor operation time.
CAUTION
1. The vertical axis drop prevention control only is performed during an emergency stop (including alarms and power
failures). It is not performed when a servo OFF command is input.
2. To operate the motor brake control output (MBR) of the 2-axis or 3-axis drive unit, input the servo OFF command to all
the servo axes in the unit.
