6.2 Enabling motor movements
The motor movement can be enabled in 2 different ways.
• Enabling the power stage
• Block P/D signals
The setting for the input ENABLE is specified during commissioning, see
chapter 5.2.6 "Setting the type of Enable".
6.2.1 Enabling the power stage
The power stage is enabled and disabled via the input ENABLE.
An error message is also reset when the power stage is disabled.
If there is no error, the output ACTIVE_OUT signals ready for operation
approximately 500 ms after the power stage is enabled.
6.2.2 Block P/D signals
P/D signals are enabled and blocked via the input GATE. Individual axes
can be selected this way in a multi-axis system.
Figure 6.1 Signal sequences in case of activation via GATE
(1) Motor step
(2) No motor steps
(3) Motor steps
No pulse may be applied for a period of 1.5 ms before and after the GATE
signal changes so that the drive can correctly process the pulse.
