Operation and application
5.5
Typical application
Open loop synchronizer debugging
1 To set the motor rated frequency (fO. 10), motor type (f5.00=2), motor rated
power (f5.02), polarity number (f5.01, it can be unset, but the rotate speed will
not be accurate), rated cuirent(f5.03) according to the motor nameplate.
2 To set the max/upper limit frequency (f0.11/10.12) according to working
conditions.
3 To set the driver as open-loop vector control. (f0.01=1)
4 Tuning motor: set f5.10=2 as rotary tuning, when the driver displays "-at- "on
screen, press "run" button to start tuning.
5 The driver will automatically save synchronous motor parameters f5.11 ~f5.14.
6 When the motor is on rotary tuning, it must be noted that tine acceleration and
deceleration time are f0.19 and f0.20, which cannot be set too small.
7 If rotary tuning is not allowed on site, static tuning(f5.10=1) should be
conducted, tine synchronous motor counter emf shall be set manually (f5.14).
Note:
There are two commonly used method to represent the synchronous motor counter
EMF.
1 Volt per thousand rotation
2 Rated frequency corresponds to the amount of voltage V50 series invertors
uses the second representation.
Note:
When the motor is on rotary tuning or running, the motor occurs unstable vibration,
skip flow fault, current limiting fault, then need to turn down the current loop
parameter properly.
Closed loop debugging
Incremental encoder parameters(F3.46=1)
To set some motor related parameters, like the motor type, rated power, rated
current, motor polarity, rated rotation speed and so on according to motor
nameplate.
To set encoder pulse number (F3.14), PG direction (F3.16), F3.54, F3.55, F3.56.
To set the control mode as closed-loop control mode (F0.01=2)
Waiting for the rotary tuning completed (if the encoder with Z signal, users do not
have to set the encoder pulse, encoder direction related parameters, these
parameters can be gotten from rotary tuning, but need to set the related function of
parameter.
