[b]608 Speed controller output limited[/b]
Cause The speed controller is at its limit for an inadmissibly long time (torque
or current limit). The permissible time is defined in P1605, the upper
speed limit when the monitoring responds, in P1606.
Synchronous motor:
In correct operation, the correctly optimized axis drive should never
reach its current limit, not even with large speed changes (changing
from rapid traverse in the positive direction to rapid traverse in the
negative direction).
P1605 = 200 ms
P1606 = 8000 rev/min
Induction motor:
Acceleration and braking with the maximum torque/current are usual in
operation, only a stalled drive (0 speed) is monitored.
P1605 = 200 ms
P1606 = 30 rev/min
1. At the first commissioning, after the software has been replaced or
the software has been upgraded, after the parameters have been entered
the ”calculate motor data” or ”calculate controller data” function
was not executed. The drive then keeps the default values (for the values
to be calculated this is zero) which can, under certain circumstances,
result in this fault (P1605 and P1606 should be adapted to the mechanical
and dynamic capabilities of the axis).
2. An undesirable input of a large torque reduction via the analog inputs
or via PROFIBUS. On PROFIBUS, this effect especially occurs when
changing over from positioning operation to operation with speed setpoint
input (check whether a torque reduction has been entered. Diagnostics
via P1717, 0%: no torque, 100%: full torque).
[b][color=#FF0000]Remedy [/color][/b]
– Check connecting cable motor/converter (phase missing, exchanged)
– Check the motor contactor
– Check the torque reduction (P1717)
– DC link voltage present?
– Check the DC link voltage (check that the screws are tight)
– Unblock the motor
– Is the motor encoder connected?
– Check the motor encoder cable screen
– Is the motor grounded (PE connection)?
– Check the encoder pulse number (P1005)
– Does the encoder cable fit to the encoder type?
– Check the direction of rotation of the encoder tracks (e.g. toothed–
wheel encoder, P1011)
Adapt parameters P1605 and P1606 to the mechanical and dynamic
capabilities of the axis. Check whether a torque reduction has been
entered (diagnostics via P1717, 0%: no torque, 100%: full torque).
For linear motors:
– Check actual value inversion
– Check the reduction in the maximum motor current (P1105) and if
required increase the value
– Check the power cable connection
– For the parallel circuit configuration, are the motors correctly assigned
and electrically connected?
– Uce monitoring function in the power section has responded (RESET
by powering off/powering on)
– Replace the power section or control module

这个报警原于驱动器工作效能下降,你的驱动器是单轴还是双轴的需要确认一下,原因两面个方向一个是6SN1123驱动器模块轴驱动模块IGBT耐压值及热稳定性不好,都会导致这个故障.第二个问题原于伺服电机,你的伺服电机去掉机械部分听一下轴承或用手轻转一下转子看是否有不均称的阻力.若有就有可能轻微的是轴承重的就是挠组或扫堂.(另外一种需经测试才可排除的可能就是611U的驱动板检测电路是否正常,如故障出在先611U的驱动板上,那么他产生的报警为误报警),具体问题欢迎来电可来邮件. 大成恒业 曲 占杨 13911826825 E-mail:dchy-88@163.com 西门子数控系统专家www.adchy.com
