2 Parameters
2.2 List of parameters
Description: Sets the parity for the Modbus protocol (p2030 = 2).
Value: 0: No parity
1: Odd parity
2: Even parity
Note: Fieldbus IF: Fieldbus interface
Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
The parameter is set to the factory setting when the protocol is reselected (p2030 = 2).
Description: Displays the effective control word 1 (STW1) of the drive for the master control.
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.
