421-SADD1 ... 424-SADD4 - Offset for reference selector 1 ...4
Source: Selector Addition Value for RSSL1 - 4
Function: Offset for reference selectors 1 to 4 (RSSL1 - RSSL4), to switch
reference sources during operation.
The offset is set via digital inputs. The parameters SADDx only display the current offset
value (switchover distance).

496-STOPR - Stop ramp
Source: Stop Ramp
Function: Stop ramp (for quick-stop\
)
The parameter determines the ramp, in the unit rpm per s, with which the motor is braked to
speed = 0. In the setting STOPR = 0 (factory setting) the motor is braked as quickly as pos-
sible at the preset torque limit TCMMX\ (quick-stop without ramp).
Quick-stop (/STOP)
The quick-stop function can be used as a safety function. The quick-stop can be triggered from various
control locations:
By way of the stop ramp parameter STOPR (_CONF) the ramp with which the motor is braked down to
speed = 0 can be specified, in the unit rpm per s. In the setting STOPR = 0 (factory setting) the motor is
braked as quickly as possible at the preset torque limit (TCMMX in subject area _TCON) (quick-stop
without ramp).
The drive control remains active, and the motor is held in this position under speed control. The quick-
stop can be activated in any control mode.
