Fast Axis Stop

Fast Axis Stop

A stop is usually triggered by PLC code using MC_Stop. However, there are special applications that require the time delay for the stop to be as small as possible. Here, bit 7 of Drive.Inputs.In.nState4 comes into play. This bit can trigger a stop directly without having to go through the PLC process image.

Drive Status 4 (manually linked):
Bit 7 = 0x80 (1000 0000) = Fast Axis Stop (digital IO interrupt)

nState4->Bit 7 variable

Bit 7 of Drive.Inputs.In.nState4 can be assigned to any event source.

Fast Axis Stop Signal Type

The "Fast Axis Stop Signal Type (optional)" list comprises six elements:

• OFF (default)
  No Fast Axis Stop is executed via the Drive.Inputs.In.nState4.7 bit.
• Rising Edge
  A Fast Axis Stop is executed on a rising edge of bit 7 of Drive.Inputs.In.nState4.
• Falling Edge
  A Fast Axis Stop is executed on a falling edge of bit 7 of Drive.Inputs.In.nState4.
• Both Edges
  A Fast Axis Stop is executed on a rising or falling edge of bit 7 of Drive.Inputs.In.nState4
• High Active
  A Fast Axis Stop is executed if bit 7 of Drive.Inputs.In.nState4 is set.
• Low Active
  A Fast Axis Stop is executed if bit 7 of Drive.Inputs.In.nState4 is not set

Fast Acceleration, Fast Deceleration, Fast Jerk

This parameterization is optional. If no values are specified, the default dynamics are applied.
