Dependency: It is not permissible to select a value of p0112 if the associated current controller clock cycle is not identical to the
basic clock cycle.
Refer to: p0110, p0111
Note: When 0 (Expert mode) is selected, the individual sampling times in p0115 can be adjusted.
After parameters have been changed, they should be saved and a POWER ON carried-out.
p0115[0...6] Sampling times for internal control loops / t_sample int ctrl
VECTOR Can be changed: C1
Data type: Floating Point
P-Group: Control
Min
0.00 [µs]
Description: Sets the sampling times for the control loops.
The default setting is made in p0112 and can only be changed for individual loops in the expert mode (p0112 = 0).
Index: [0] = Current controller
[1] = Speed Controller
[2] = Flux controller
[3] = Setpoint channel
[4] = Pos ctr (beingDev)
[5] = Positioning (being developed)
[6] = Techn. ctrl
Dependency: The sampling times can only be separately set if p0112 is set to 0 (expert mode). The current controller sampling
times must be set so that they are identical to the selected basis clock cycle (p0111 and p0110).
Higher-level controls must be calculated in integral ratios to lower-level controls (e.g. p0115[1] = N * p0115[0];
where N is a whole number).
Refer to: p0110, p0111, p0112
Note: if a control loop does not exist (e.g. positioning), a 0 is assigned to the parameter value.
For function modules that can be activated (e.g. technology controller), the parameters values are pre-assigned.
For the active line module (ALM), the currents and DC link voltage controllers operate with the same sampling time.
For the basic line module (BLM), the DC link voltage measurement operates in the current controller clock cycle.
After parameters have been changed, they should be saved and a POWER ON carried-out.
p0117 Current controller computation deadtime mode / I_ctrl t_dead mode
CU Can be changed: U, T
Data type: Integer16
P-Group: Control
Min
0
Description: Sets the mode for the computation deadtime of the current controller.
0: Offset (shifted) clocking, minimum computation deadtime of each drive, automatic setting
1: Clocking at the same time, the deadtime aligns itself to the deadtime of the latest drive, automatic setting
2: Manual setting of the computation deadtime, early transfer
3: Manual setting of the computation deadtime, late transfer
4-6: As for 0-2, however, no early transfers are set for vectors
