Message value: %1 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: 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 mult iple of the current controller clock cycle. 3: Instant of the actual value sensi ng 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 clock cycle. 5: Instant of the setpoint acceptance To >= Bus cycle time Tdp or To = 0. 6: Instant of the setpoint acceptance To is not an in teger multiple of the current controller clock cycle. 7: Master application cycle time Tmapc is not an in teger 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 modi fied with respect to the first time that the connection was established. 10: Instant of the setpoint acceptance not To <= data exchange time Tdx + To_min. 11: Master application cycle time Tmapc > 14 or Tmapc = 0. 12: PLL tolerance window Tpll_w > Tpll_w_max. 13: Bus cycle time Tdp is not a mult iple of all basic clock cycles p0110[x]. 14: For COMM BOARD with the setting To - 1 = Tdp - Ti, the instant of the setpoint acceptance is not To <= Data exchange time Tdx + 2 * To_min. 15: This configuration is not permitted for Tdp < 1 ms. 16: Instant of the actual value sensing Ti is less than the permi tted value (COMM BOARD: Ti >= 2). 17: The setting (To + Ti = Tdp + 2) is not permitted for COMM BOARD. Remedy: - adapt the parameterizing telegram. - adapt the current and speed controller clock cycle. Re alarm value = 9: - carry out a POWER ON. Re alarm value = 15: - check the number of specific drive object types in the configuration. Note: IF1: Interface 1 PB: PROFIBUS PN: PROFINET
