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
Programming
IPOBRKA(<axis>[,<instant in time>])
Block change criterion: Deceleration ramp IPOBRKA:
Effective: Modal
<axis>: Channel axis name (X, Y, ....)
Time of the block change, referred to the braking ramp as a %:
• 100% = start of the braking ramp
• 0% = end of the braking ramp, the same significance as
IPOENDA
<instant in time>:
Type: REAL
IPOBRKA is deactivated for the corresponding access when an axis end-of-motion criterion
(
FINEA, COARSEA , IPOENDA ) is next programmed for the axis.
Additional block change criterion: "Tolerance window" (ADISPOSA)
A tolerance window around the end of block (either as actual or setpoint position) can be
defined as additional block change criterion. Then, two conditions must be fulfilled for the
block change:
● Block change criterion: "Braking ramp"
● Block change criterion: "Tolerance window"
