2.2 List of parameters
Note: For function modules that can be activated (e.g. technology controller), the parameters values are pre-assigned.
For power unit type PM340 (r0203), only current controller sampling times of 250 µs or 500 µs can be set. The
minimum current controller clock cycle is otherwise 125 µs (SINAMICS G: 250 µs), the maximum current controller
clock cycle is 500 µs. The minimum speed controller clock cycle for SINAMICS G is 1 ms.
Current controller clock cycles less than 250 µs are restricted by the number of drives or by the number of power
units connected in parallel (also see F01340).
For chassis power units connected in parallel, it is recommended to connect the DRIVE-CLiQ cables (partially) in
parallel between the Control Unit and the individual Motor Modules.
For D410-2, the current controller sampling times can only be permanently changed with p0112 = 0 (e.g. to 250 µs).

Description: Sets the sampling times for the control loops.
The default setting is made using p0112 and can only be individually changed for p0112 = 0 (expert).
Recommendation: When changing the sampling times of the current and speed controllers (also refer to p0115), then we recommend
that after exiting commissioning (p0009 = 0) the controller settings are re-calculated using p0340 = 4.
Index: [0] = Current controller
[1] = Speed controller
[2] = Flux controller
[3] = Setpoint channel
[4] = Position controller
[5] = Positioning
[6] = Technology controller
Dependency: The sampling times can only be separately set if p0112 is 0 (expert). If a sampling time is modified in the expert
mode, then all of the sampling times with higher indices are automatically changed in the same ratio as the sampling
time itself was changed. Slower time slices are only taken if the calculated sampling time is also permitted. Upper
limit is 8 ms.
Higher-level controls must be calculated in integral ratios to lower-level controls (e.g. p0115[1] = N * p0115[0]; where
N is an integer number). The sampling time of the speed controller (p0115[1]) can have as a maximum a value of
800% of the current controller sampling time (p0115[0]).
For servo drives, the maximum sampling time of the current controller is 250 µs and for vector drives, 500 µs.
The sampling times for setpoint channel (p0115[3]), position controller (p0115[4]), positioning (p0115[5]) and
technology controller (p0115[6]) must have at least 2x the value of the current controller sampling time (p0115[0]).
Refer to: r0110, r0111, p0112
Note: For function modules that can be activated (e.g. technology controller), the parameters values are pre-assigned.
For the Active Line Module (ALM) and Smart Line Module (SLM), the current and DC link voltage controllers operate
with the same sampling time. For ALM/SLM the maximum current controller clock cycle is 400 µs.
For the Basic Line Module (BLM), the DC link voltage measurement operates in the current controller sampling time.
For BLM booksize, only the current controller sampling time of 250 µs is permitted. For BLM chassis, only the current
controller sampling time of 2000 µs is permitted.
For power unit type PM340 (r0203), only current controller sampling times of 62.5 µs, 125 µs, 250 µs and 500 µs can
be set. The maximum current controller clock cycle for servo drives and the minimum current controller clock cycle for
vector drives is 250 µs.
If sampling times in p0115 are individually changed for p0112 = 0 (expert) then it must always be observed that the
selected sampling times of the setpoint channel (p0115[3]), position controller (p0115[4]), positioning (p0115[5]) and
technology controller (p0115[6]) are always greater than or equal to twice the current controller sampling time
(p0115[0]).
