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.
Reaction: 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 cycle factor changed to %1
Parameters: %1 = String (new IPO cycle)
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 PROFIBUS DP because of the
modified DP cycle in the SDB (MD 10050 SYSCLOCK_CYCLE_TIME).
Reaction: 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:
Definitions: The PLC cycle divisor was set to a value which was not an integral multiple of the IPO cycle divisor.
The divisor (MD 10 074 PLC_IPO_TIME_RATIO) has been increased.
Reaction: Alarm display.
Remedy: Adapt machine data.
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)
Definitions: MD 10060 POSCTRL_SYSCLOCK_TIME_RATIO has been modified because of the modified DP
cycle in SDB1000 (10050 SYSCLOCK_CYCLE_TIME).
Reaction: Alarm display.
Remedy: Machine data 10060 POSCTRL_SYSCLOCK_TIME_RATIO RATIO has been modified.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
4113 Sysclock cycle changed to %1 ms
Parameters: %1 = String (new PLC cycle)
Definitions: MD 10050 SYSCLOCK_CYCLE_TIME has been modified because of the modified DP cycle in the
SDB.
Reaction: Alarm display.
Remedy: Machine data 10050 SYSCLOCK_CYCLE_TIME has been modified.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
