Note: A change only becomes effective after a POWER ON.
The parameter is not influenced by setting the factory setting.
Description: Display for "offset clocking".
Depending on the particular case, the value is interpreted differently:
Case 1:
The PWM clock cycle (1/p1800[D]) is greater than the current controller clock cycle (p115[0]) and the ratio between
the PWM clock cycle and the current controller clock cycle and is an integer and even multiple of it (e.g. p0115[0] =
125 µs, p1800[D] = 4 kHz, 2 kHz, 1 kHz).
The value displayed refers to:
- the phase shift in the current-controller cycles to be applied by the power unit.
Case 2:
The PWM clock cycle (1/p1800[D]) is less than or equal to the current controller clock cycle (p0115[0]) and the ratio
between the current controller clock cycle and the PWM clock cycle is an integer and even multiple of it (e.g.
p0115[0] = 125 µs, p1800[D] = 8 kHz, 16 kHz).
The value 1 displayed means that:
- the power unit is to apply a phase shift of 180 ° (from the PWM cycle).
A value of 0 displayed on all power units of the drive line-up means the following:
- the general conditions of the "offset clocking" (see p1815) are not fulfilled, i.e. no power unit is clocked with an
offset.
Dependency: Refer to: p0108, r0108, p0115, p1800, p1815, p1816, p1818
Note: For reasons of compatibility, the parameter is an adjustable parameter. However, it functions solely as a display
parameter. This means that factory setting -1 no longer has any significance and is only available for reasons of
compatibility.
Description: Sets the phase sequence reversal for the motor.
If the motor does not rotate in the required direction, then the output phase sequence can be reversed using this
parameter. This means that with the same setpoint, the motor direction is reversed without reversing the encoder
actual value.
When a speed encoder is being used, it may be necessary to also invert the encoder actual value (p0410).
Value: 0: OFF
1: ON
Dependency: Refer to: p1821
Caution: For 12-pulse converters with 30° offset angle for system 2, for a direction of rotation reversal, the phase offset
changes by 60° as the sign of the angle offset changes. This can be adapted in p1810.15.
Changing the direction using p1820 or p1821 is not recognized by the "Safe Direction without encoder". As a
consequence, the limit provided by SDI (Safe Direction) from r9733 no longer functions.
Note: This setting can only be changed when the pulses are inhibited.
p1821 can be used to reverse the phase sequence and encoder actual value.
