03/2009
Cause: The input current of the Terminal Module analog input has exceeded the threshold value parameter-
ized in p4061[x].
This fault can only occur if p4056[x] = 3 (4 ... 20 mA with monitoring) is set.
Index x = 0: Analog input 0 (X522.1 to .3)
Index x = 1: Analog input 1 (X522.4 to .5)
Fault value (r0949, interpret decimal):
The component number (p0151) of the module involved is specified at the units, tens and hundreds
digit.
The thousands digit specifies the analog input involved: 0: Analog input 0 (AI 0), 1: Analog input 1 (AI
1)
Remedy: Check the connection to the signal source for interruptions.
Check the magnitude of the injected current - it is possible that the infed signal is too low.
Please note that the input has a load resistance of 250 Ohm.
The input current measured by the Terminal Module can be read out from r4052[x].
203506 <location>24 V power supply missing
Message %1
value:
Drive object: A_INF, B_INF, CU_I, CU_LINK, CU_S, HUB, S_INF, SERVO, TB30, TM15, TM15DI_DO, TM17,
TM31, TM41, TM54F_MA, TM54F_SL, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The 24 V power supply for the digital outputs (X124) is missing.
Remedy: Check the terminals for the power supply voltage (X124, L1+, M).
203550 <location>TM: Speed setpoint filter natural frequency > Shannon
frequency
Message -
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The natural filter frequency of the speed setpoint filter (p1417) is greater than the Shannon frequency.
The Shannon frequency is calculated according to the following formula: 0.5 / p0115[0]
See also: p1417
Remedy: Reduce the natural frequency of the speed setpoint filter (PT2 low pass) (p1417).
203590 <location>TM: Module not ready
Message %1
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE)
SERVO: NONE (ENCODER, IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: OFF2 (ENCODER, IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The Terminal Module involved does not send a ready signal and no valid cyclic data.
Fault value (r0949, interpret decimal):
Drive object number of the Terminal Module involved.
Remedy: - check the 24 V power supply.
- check the DRIVE-CLiQ connection.
- check whether the sampling time of the drive object involved is not equal to zero (p4099[0]).
205000 <location>Power unit: Heat sink overtemperature

value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: NONE
