For a power unit type PM340 (refer to r0203), only current controller sampling times of 62.5 µs, 125 µs, 250µs and
500µs can be set. The minimum current controller clock cycle for vector drives and the maximum current controller
clock cycle for servodrives is 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).
Recommend.: When changing the sampling times of the current and velocity 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] = Velocity controller
[2] = Flux controller
[3] = Setpoint channel
[4] = Pos 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 sam-
pling 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 a whole number). The sampling time of the velocity 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.
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 oper-
ate 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 250µs is permitted. For BLM chassis, only the cur-
rent controller sampling time of 2000µs is permitted.
For a power unit type PM340 (refer to r0203), only current controller sampling times of 62.5 µs, 125 µs, 250µs and
500µs can be set. The minimum current controller clock cycle for vector drives and the maximum current controller
clock cycle for servodrives is 250 µs.
