The actual flying restart process can be adjusted via the following parameters:
0x2BA1 | 0x33A1 - Flying restart: Current
0x2BA2 | 0x33A2 - Flying restart: Start frequency
0x2BA3 | 0x33A3 - Flying restart: Integration time
0x2BA4 | 0x33A4 - Flying restart: Min. deviation
0x2BA5 | 0x33A5 - Flying restart: Delay time
Current injected in the motor by the flying restart algorithm to identify the current speed.
• Selection in [%] based on the rated motor current (0x6075
or 0x6875 for axis B).
• The higher the current the higher the torque imposed upon the motor.
• If the current is too low, a wrong speed can be detected.

Start frequency of the flying restart algorithm
• If it can be anticipated at which frequency the motor "caught" most frequently in a flying restart process, this
frequency is to be set here.

Integration time of the angle controller
• The Lenze setting is adapted to machines with an average power.
• A guide value for the integration time can be calculated as a function of the motor power with the following
equation: Ti = 1.1 μ/W * rated motor power
+9.4ms
• For accelerating the search process, this guide value can be reduced.
• If the flying restart frequency oscillates too much, the integration time has to be increased again.
• A longer integration time increases the time for "catching" the drive.

To avoid starting a flying restart process at short-time controller inhibit, a time can be set here for the minimum
active controller inhibit time before a flying restart process is activated.
• Since a pulse inhibit > 500 ms causes a controller inhibit, this also applies to the pulse inhibit.
