Block change criterion: "Braking ramp" (IPOBRKA)
If, when activating the block change criterion "brake ramp", a value is programmed for the
optional parameter <instant in time>, then this becomes effective for the next positioning
motion and is written into the setting data synchronized to the main run. If no value is specified
for the block change instant in time, then the actual value of the setting data is effective.
SD43600 $SA_IPOBRAKE_BLOCK_EXCHANGE
The time at which the block change can be realized is specified as a percentage of the braking
ramp:
● 100% = start of the braking ramp
● 0% = end of the braking ramp, the same significance as block change criterion IPOENDA
