Note:
A change only becomes effective after booting.
If one of the following secondary conditions is not fulfilled, then none of the power units from the subgroup are
clocked with an offset.
Secondary conditions for clocking with an offset:
- the PWM frequency (p1800[D]) of all power units in the subgroup must be the same.
- the PWM frequency (p1800[D]) must be the same in all drive data sets in the subgroup.
- the following must apply for the ratio between the PWM cycle (1/p1800[D]) and the current controller cycle
(p0115[0]):
The ratio (1/p1800[D]) / (p0115[0]) must be an even integer number (2, 4, 6, ...) for all power units in the subgroup.
or
The ratio (p0115[0]) / (1/p1800[D]) must be an integer number (1, 2, 3, ...) for all power units in the subgroup.
Description:
Sets manual setting and overwriting of automatically determined phase shift for "offset clocking".
For p1816 = -1, the following applies:
Automatic mode. The phase shift value is automatically determined.
For p1816 = 0 ... 16, the following applies:
Manual mode. The user should define the phase shift value as follows:
1. PWM cycle (1/p1800) > current controller cycle (p0115[0])
The power unit executes a phase shift from Tshift = current controller cycle (p0115[0]) * p1816.
2. PWM cycle (1/p1800) <= current controller clock cycle (p0115[0])
For p1816 >= 1, the power unit executes a phase shift from Tshift = PWM cycle/2.
Dependency:
Refer to: r0116, p1800, p1819
Description:
Sets the minimum ratio between the pulse frequency and the output frequency.
Notice:
If the ratio between the pulse frequency and the output frequency is reduced, then oscillations can occur in the output
current that can result in significant levels of current ripple with the appropriate negative effects.
Note:
When the maximum speed is changed, the pulse frequency p1800 is automatically limited to this minimum ratio. It is
not permissible to reduce the pulse frequency if this would result in this ratio being undershot.
Description:
Sets the phase shift for offset clocking.
For the first active power unit, it is specified whether clocking is to start at 0° (value = 0) or 180° (value = 1). All other
active power units are clocked alternately according to the setting made here.
