Drive-Integrated Esr; Configuring Drive-Integrated Stopping (Esrs) - Siemens SINUMERIK 840D sl Programming Manual

Work preparation
3.21 Extended stop and retract (ESR)
Requirements
● A stopping axis is configured for the NC-controlled stopping in the channel:
MD37500 $MA_ESR_REACTION = 22
● ESR must be enabled for this axis:
$AA_ESR_ENABLE = 1
● Delay times are defined:
MD21380 $MC_ESR_DELAY_TIME1 (delay time, ESR axes)
MD21381 $MC_ESR_DELAY_TIME2 (ESR time for interpolatory braking)
Execution
This axis continues interpolating as programmed for the time period set in MD21380: After the
time delay specified in MD21380 has expired, controlled braking (ramp stop) is initiated: The
time period in MD21381 is the maximum available for the interpolatory controlled braking. After
this period expires, fast braking with subsequent tracking is initiated.
Example
Stopping a single axis:
Program code
MD37500 $MC_ESR_REACTION[AX1] = 22
MD21380 $MC_ESR_DELAY_TIME1[AX1] = 0.3
MD21381 $MC_ESR_DELAY_TIME2[AX1] = 0.06
...
$AA_ESR_ENABLE[AX1]=1
$AA_ESR_TRIGGER[AX1]=1

Configuring drive-integrated stopping (ESRS)

The drive parameters for "stopping" of the drive-integrated ESR function are configured using
the ESRS(...) function.
