Flying restart with encoder

Description
The flying restart function behaves differently with V/f control and vector control:
● V/f characteristic (p1300 < 20):
● Vector control with encoder:
9.3.5.3

Parameters

• p1200
• p1202
• p1203
• r1204
• r1205

Flying restart without encoder (see "Flying restart without encoder")
Since the speed is known from the start, the motor can be magnetized immediately at the
appropriate frequency. The duration of magnetization is specified in p0346. Once the
excitation build-up time has elapsed, the ramp-function generator is set to the actual
speed value and the motor ramped up to the current setpoint speed.
WARNING
When the flying restart (p1200) function is active, the drive may still be accelerated by
the detection current despite the fact that it is at standstill and the setpoint is 0.
For this reason, entering the area around the drive when it is in this condition can cause
death, serious injury, or considerable material damage.
Flying restart operating mode
• 0: Flying restart inactive
• 1: Flying restart is always active (start in the setpoint direction).
• 2: Flying restart is active after: power-on, fault, OFF2 (start in the setpoint
direction).
• 3: Flying restart is active after: fault, OFF2. (start in the setpoint
direction).
• 4: Flying restart is always active (start only in the setpoint direction).
• 5: Flying restart is active after: power-on, fault, OFF2 (start only in the
setpoint direction).
• 6: Flying restart is active after: fault, OFF2 (start only in the setpoint
direction).
