PLL: Activates PLL control.
PLL control synchronizes the inverter with the SYNC telegrams of the CAN bus or the SYNC signal
of the EtherCAT bus.

PLL phase-offset: Time offset value between the arrival of the SYNC telegram and the phase
position of the cycle time on the inverter.
Value range in µs: -32768 ... -800 ... 32767

PLL gain: Proportional gain of PLL control.
The gain must be reduced when the jitter of the SYNC telegrams increases.
Value range in %: 0.0 ... 20,0 ... 100.0

PLL low pass: Determines the limit frequency of the low pass filter of PLL control.
The time must be increased when the jitter of the SYNC telegrams increases.
Value range in ms: 0.0 ... 40,0 ... 200.1

PLL status: Shows the status of PLL control.
• Bit-0: PLL status
• Bit-1: PLL status
00 PLL engaged
01 Engaged, but more than half the control range is utilized (frequency too high).
10 Engaged, but more than half the control range is utilized (frequency too low).
11 PLL not engaged.
• Bit-2: Is 1 when PLL has extended the internal cycle time (A150).
• Bit-3: Is 1 when control hits the limits of the control range.
• Bit-4: Is 1 when the measured cycle time (G96) is greater than the specification (G98).
• Bit-5: Is 1 when G90 = inactive (PLL is deactivated).
• Bit-6: Reserved
• Bit-7: Reserved
