4.25.7.15.5.3 Configuration registers with SDC
SDC configuration
Name:
SDCConfig01
This register can be used to enable/disable additional SDC information.
Enabling/disabling the SDC information shows or hides additional cyclic registers. It is comparable to the two
variants of the standard function model with and without SDC information.
Data type
Value
USINT

When the "SDC information" bit is enabled, the "EncOK01" bit is shown in the Automation Studio I/O mapping. This bit is linked to the ModulOK bit and
always indicates its value.
Note:
Neither SDC information nor SDC life sign monitoring is permitted to be changed at runtime.
Module configuration 1 with SDC
The Module configuration 1 register is ignored in the standard function model with SDC information enabled. The
module behaves as if the module configuration were described as follows:

Motor settling time
Name:
MotorSettlingTime01
This register determines the motor setting time. The motor settling time determines the minimum time between
when the motor is powered on to when the DrvOk bit is set (see "Error status"). The setting is made in steps of 10 ms.
Data type
Value
Information
USINT
1 to 255
10 ms to 2.55 s, default: 10 ms
Turn-off delay
Name:
DelayedCurrentSwitchOff01
When the SDC life sign monitoring is triggered (i.e. the NetTime timestamp is in the past) the motor is decelerated
at rated current with speed setpoint = 0.
Then the motor is switched off after the delay configured with this register.
Data type
Value

USINT
0 to 255
0 to 25.5 ms in steps of 100 ms (default: 100 ms)
