2.2 List of parameters
Notice: The master control only influences control word 1 and speed setpoint 1. Other control word/setpoints can be 
transferred from another automation device.
Note: OC: Operating condition
Description: Sets the processing mode for PROFIdrive STW1.10 "master control by PLC".
Generally, control world 1 is received with the first receive word (PZD1) (this is in conformance to the PROFIdrive 
profile). The behavior of STW1.10 = 0 corresponds to that of the PROFIdrive profile. For other applications that 
deviate from this, the behavior can be adapted using this particular parameter.
Value: 0: Freeze setpoints and continue to process sign-of-life
1: Freeze setpoints and sign-of-life
2: Do not freeze setpoints
Recommendation: Do not change the setting p2037 = 0.
Note: If the STW1 is not transferred according to the PROFIdrive with PZD1 (with bit 10 "master control by PLC"), then 
p2037 should be set to 2.
Description: Sets the interface mode of the PROFIdrive control words and status words.
When selecting a telegram via p0922 (p2079), this parameter influences the device-specific assignment of the bits in 
the control and status words.
Value: 0: SINAMICS
2: VIK-NAMUR
Dependency: Refer to: p0922, p2079
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: - For p0922 (p2079) = 1, 350 ... 999, p2038 is automatically set to 0.
- For p0922 (p2079) = 20, p2038 is automatically set to 2.
It is not then possible to change p2038.
Description: The serial interface for the debug monitor is COM1 (commissioning interface, RS232) or COM2 (fieldbus interface, 
RS485).
Value = 0: De-activated
Value = 1: COM1, commissioning protocol is de-activated
Value = 2: COM2, field bus is de-activated
Value = 3: Reserved
Note: Value = 2 is only possible for Control Units with RS485 as a field bus interface.
