more than 16 ms resulted. The boundary value for the drive actuator 611D is however 16
ms.
Reactions: - Alarm display.
Remedy: No remedial measures are required. The alarm display is canceled with Reset.
Program Con-
tinuation:
Switch control OFF - ON.
4102 Default values for drive cycle times differ
Definitions: External control modules of the 611D bus and the controls within the CCU3 module have
different default values for the current and speed control cycle times.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: External control modules of the 611D bus and the controls within the CCU3 module have
different default values for the current and speed control cycle times.
Check the specified values and modify accordingly (see MD_CURRCTRL_CYCLE_TIME
and MD_SPEEDCTRL_CYCLE_TIME).
Program Con-
tinuation:
Switch control OFF - ON.
4110 IPO factor increased to %1
Parameters: %1 = String (new IPO cycle time)
Definitions: The IPO cycle divisor was set to a value which was not an integral multiple of the position
control cycle divisor. The divisor (MD 10070 IPO_SYSCLOCK_TIME_RATIO) was
increased. IPO_SYSCLOCK_TIME_RATIO has been modified on systems with PROFI-
BUS DP because of the modified DP cycle in SDB1000 (MD 10050
SYSCLOCK_CYCLE_TIME).
Reactions: - Alarm display.
Remedy: Machine data 10070 IPO_SYSCLOCK_TIME_RATIO has been modified.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
4111 PLC cycle increased to %1 ms
Parameters: %1 = String (new PLC cycle time)
Definitions: The PLC cycle divisor was set to a value which was not an integral multiple of the IPO
cycle divisor. The divisor (MD 10074 PLC_IPO_TIME_RATIO ) has been increased. MD
10074 PLC_IPO_TIME_RATIO has been modified on systems with PROFIBUS DP
because of the modified DP cycle in SDB1000 (MD 10050 SYSCLOCK_CYCLE_TIME).
Reactions: - Alarm display.
Remedy: Machine data 10074 PLC_IPO_TIME_RATIO has been modified.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
4112 Servo cycle changed to %1 ms
Parameters: %1 = String (new servo cycle time)
Definitions: MD 10060 POSCTRL_SYSCLOCK_TIME_RATIO has been modified on systems with
PROFIBUS DP because of the modified DP cycle in SDB1000 (10050
SYSCLOCK_CYCLE_TIME).
Reactions: - Alarm display.
Remedy: Machine data 10060 POSCTRL_SYSCLOCK_TIME_RATIO RATIO has been modified.
