203Bh I2t Parameters

Function

This object contains the parameters for I2t monitoring.

I2t monitoring is activated by entering a value greater than 0 in 203Bh:01 and 203Bh:02 and a value greater than 1000 in 6073h (see I2t Motor overload protection).

With one exception, I2t monitoring can only be used for closed loop mode: If I2t is activated in open loop mode, the current is reduced to the smaller of 203Bh:01h, 6073h and 2031h.

Description

The subindices are divided into two groups: subindex 01h and 02h contain parameters for control, subindices 03h to 06h are status values. The functions are as follows:

  • 01h: The rated current specified in the motor data sheet is entered here in mA. This must be smaller than the current entered in 2031h and 6073h, otherwise monitoring is not activated. The specified value is interpreted as root mean square.
  • 02h: Specifies the maximum duration of the maximum current (6073h) in ms.
  • 03h: Threshold, specifies the limit in A2ms that determines whether the maximum current or rated current is switched to.
  • 04h: CalcValue, specifies the calculated value in A2ms that is compared with the threshold for setting the current.
  • 05h: LimitedCurrent, contains the momentary current as root mean square set by I2t.
  • 06h: Current status. If the sub-entry value is "0", I2t is deactivated; if the value is "1", I2t is activated.
