Delay time

The set current limit can be briefly reached in acceleration processes and deceleration processes or under load peaks. Unintentionally sensitive response by the speed monitoring can be prevented by setting the deceleration time as appropriate. The current limit must be reached without interruption for the duration of the delay time before the monitoring responds.

Reset time factor

When the setting limit of the speed controller is reached, a counter for the delay time is incremented each millisecond. If the speed controller leaves its control limit before the delay time expires, the counter will be decremented until 0 is reached. You can use this parameter to set a factor that specifies how fast the counter decrements when leaving the control output limit compared to the delay time. This factor is usually set to "1", which means the counter is decremented every millisecond. If the factor is set to "2", the counter is decremented by 2 every millisecond, etc.

Stop functions

Behavior at standstill

The following settings can be made for behavior at standstill:

  • Drive energized (brake released)
  • Drive not energized (brake applied)

The stop function is active if enable is revoked (stop with FCB 13/14), if no operating mode is selected (FCB 02), and if the stop by setpoint function is enabled. For drives without encoder, this setting is ignored, which means the brake function is always active

Negative SW limit switch

Position of the negative software limit switch (in user units).

Index: 8572.4

Positive SW limit switch

Position of the positive software limit switch (in user units).

Index: 8572.6

HW limit switch hit response

  • No response
  • Emergency stop + output stage inhibit
  • Emergency stop + output stage inhibit with self-reset

Index: 8572.1

SW limit switch hit response

  • No response
  • Emergency stop + output stage inhibit
  • Emergency stop + output stage inhibit with self-reset

Index: 8572.2

Use HW limit switches of DT1 also in DT2

For monitoring the hardware limit switches, the hardware limit switches of drive train 1 are also used for drive train 2. This setting is useful if the same drive is used in both drive trains with different control modes or encoder configurations.
