Cause:
Parameterization for isochronous operation is not permissible.
Alarm value (r2124, interpret decimal):
0: Bus cycle time Tdp < 0.5 ms.
1: Bus cycle time Tdp > 32 ms.
2: Bus cycle time Tdp is not an integer multiple of the current controller sampling time.
3: Instant of the actual value sensing Ti > Bus cycle time Tdp or Ti = 0.
4: Instant of the actual value sensing Ti is not an integer multiple of the current controller sampling time.
5: Instant of the setpoint acceptance To >= Bus cycle time Tdp or To = 0.
6: Instant of the setpoint acceptance To is not an integer multiple of the current controller sampling time.
7: Controller application cycle time Tmapc is not an integer multiple of the speed controller sampling time.
8: Bus reserve bus cycle time Tdp - Data exchange time Tdx less than two current controller sampling times.
10: Instant of the setpoint acceptance To <= data exchange time Tdx + current controller sampling time
11: Controller application cycle time Tmapc > 14 x Tdp or Tmapc = 0.
12: PLL tolerance window Tpll_w > Tpll_w_max.
13: Bus cycle time Tdp is not a multiple of the speed controller clock cycle.
Remedy:
- Adapt the bus parameterization Tdp, Ti, To.
- Adapt the sampling time for the current controller or speed controller.
For alarm value = 10:
- Reduce Tdx by using fewer bus participants or shorter telegrams.

A01904
PN: Controller setting of the PZD telegram rejected
Message class:
Communication error to the higher-level control system (9)
Message value:
%1
Component:
None
Response:
NONE
Acknowledgment: NONE
Cause:
A controller attempts to set a PZD telegram. The setting is not applied.
Alarm value (r2124, interpret decimal):
3: Controllers have no function rights for making changes.
4: Telegram cannot be set as a result of the drive configuration.
See also: r0922 (PROFIdrive PZD telegram selection)
Remedy:
Check and align the telegram settings in the drive project and in the controller.
A01905
PN: Controller setting to activate the channel diagnostics rejected
Message class:
Communication error to the higher-level control system (9)
Message value:
%1
Component:
Control Unit (CU)
Response:
NONE
Acknowledgment: NONE
Cause:
A controller attempted to change the activation of the channel diagnostics. The setting is not applied as the controller does
not have the function rights to make a change.
Alarm value (r2124, interpret decimal):
1: Channel diagnostics are activated. Controller attempts to deactivate them.
2: Channel diagnostics are not activated. Controller attempts to activate them.
Remedy:
Activate channel diagnostics in the bus configuration and check and align function rights in the drive.
