Overview of Alarms
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring
telegram.
Alarm value (r2124, decimal):
50: Syntax error.
51: Connection established to more drive objects than configured in the device. The drive
objects for process data exchange and their sequence was defined using p0978.
52: Too many data words for input or output to a drive object. A max. of 16 words is
permitted for SERVO and VECTOR; max. 5 words, for A_INFEED, TB30, TM31 and
CU320.
53: Uneven number of bytes for input or output.
Remedy: Check the bus configuring on the master and slave sides.
Re alarm value = 51:
Check the list of the drive objects with process data exchange (p0978). With p0978[x] = 0,
all of the following drive objects in the list are excluded from the process data exchange.
201901 <location>PROFIBUS: Parameterizing telegram error
Reaction: NONE
Acknowledge: NONE
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
201902 <location>PROFIBUS: Parameterizing telegram not permissible
Reaction: NONE
Acknowledge: NONE
Cause: Alarm value (r2124, decimal):
0: Bus cycle time Tdp < 0.5 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 To >= 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].
14: Instant in time that the setpoint is accepted To <= Data Exchange Time Tdx +
2*To_min, if Comm-Board and (To-1 = Tdp - Ti).
15:This configuration is not permitted for tdp < 1ms.
