Cause:
A PROFIBUS master attempts to establish a connection using an incorrect parameterizing telegram.
Alarm value (r2124, decimal):
1: Incorrect parameterizing bits
10: Illegal length of an optional parameterizing block
11: Illegal ID of an optional parameterizing block
20: Double parameterizing block for clock synchronization
21: Incorrect parameterizing block for clock synchronization
22: Incorrect parameterizing bits for clock synchronization
Remedy:
Check the bus configuration:
- bus addresses
- slave configuring
Reaction upon F:
NONE (OFF1)
Acknowledge
IMMEDIATELY
upon F:
A01902
PROFIBUS: Parameterizing telegram not permissible
Reaction:
NONE
Acknowledge:
NONE
Cause:
Alarm value (r2124, decimal):
0: Bus cycle time Tdp < 1 ms
1: Bus cycle time Tdp > 32 ms
2: Bus cycle time Tdp is not a integer multiple of the current controller clock cycle.
3: Instant of the actual value sensing Ti > Bus cycle time Tdp
4: Instant of the actual value sensing Ti is not an integer multiple of the current controller clock cycle.
5: Instant of the setpoint transfer Ti > = Bus cycle time Tdp
6: Instant of the setpoint transfer To is not an integer multiple of the current controller clock cycle.
7: Master application cycle time Tmapc is not an integer multiple of the speed controller clock cycle.
8: Bus reserve bus cycle time Tdp - data exchange time Tdx less than two current controller clock cycles.
9: Bus cycle time Tdp has been modified with respect to the first time that the connection was established.
10: Instant of the setpoint transfer To <= data exchange time Tdx + To_min.
11: Master application cycle time Tmapc > 14.
12: PLL tolerance window Tpll_w > Tpll_w_max.
13: Bus cycle time Tdp is not a multiple of all basic clock cycles p0110[x].
Remedy:
- adapt the parameterizing telegram.
- adapt the current and speed controller clock cycle.
A01903 (F)
COMM INT: Receive configuration data not valid
Reaction:
NONE
Acknowledge:
NONE
Cause:
The drive unit did not accept the receive-configuration data.
Alarm value (r2124, decimal):
Return value of the receive-configuration data check.
0: Configuration accepted.
1: Drive overflow.
2: Data length overflow.
3: Data length uneven.
4: Setting data for synchronization not accepted.
5: Drive still not in cyclic operation.
6: Buffer system not accepted.
7: Cyclic channel length too short for this setting.
8: Cyclic channel address not initialized.
9: 3-buffer system not permitted.
10: DRIVE-CLiQ fault.
11: CU link fault.
12: CX32 not in cyclic operation.
Remedy:
Check the receive configuration data.
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowledge
IMMEDIATELY
