Rectifier Diode(Standard Diode)
Rectifier Diode(Standard Diode) utilizes the unidirectional conductivity of the diode, which can convert the alternating current of alternating direction to a pulsating direct current of a single direction. Rectifier diode – diode designed for rectifying alternating current (mostly with low power frequency – 50 Hz at high power emitted during load). The main task of the rectifier diode is to convert AC voltage into DC voltage through application in rectifier bridges. The variant of rectifier diodewith the Schottky barrier is particularly valued in digital electronics.

Need to set: armature current, excitation current, armature voltage, excitation voltage, feedback mode, given source, start source, automatic tuning optimization, generally these parameters are sufficient
The DC governor is an all-digital rectifier with three-phase input and rated armature current from 15a to 2200a. The compact rectifier can be used in parallel to provide up to 12000a of current, and the excitation circuit can provide up to 85a of current (this current Depending on armature rated current)
(1) 6ra70 governor parameter setting and self-optimizing debugging settings
P051=21; Restore factory settings (use this setting if you are not sure which parameters have been modified)
P051=40; Allow modification of parameters
P052=3 ; Show all parameters
P100=armature rated current (this can be set with reference to the motor nameplate during commissioning)
P101=armature rated voltage (this can be set with reference to the motor nameplate during commissioning)
P102=Excitation rated current (this can be set with reference to the motor nameplate during commissioning)
P104, p105, p106, p107, p108, p109, p114, default
P082=1, the excitation circuit is closed with the main circuit contactor
P083=3, the speed feedback signal is provided by emf, 1=xt104 xt103 provides (speed feedback), 2=encoder feedback
If you select p083=2, please set the following parameters
P140=1, encoder type 1
P141=1024, encoder pulse number
P142=1, encoder output
P143=3000, set the maximum running speed of the motor
If you select p083=1, please set the following parameters
P741=Tachometer generator feedback voltage. Algorithm: For example, the speed motor nameplate 110v 2000 rpm, the motor rated speed 1500 rpm, then please set the p741 voltage to 83v.
Optimization operation: (we only do current loop optimization here)
P051=25, pre-control of armature and excitation and optimal operation of current regulator
Start the governor, 6ra70 will automatically run, optimize the current loop and excitation parameters.
Siemens DC governor 6RA70 quick setting method
In the use of the DC governor, it is sometimes necessary to restore the parameters to the factory settings or reset the parameters. Which parameters need to be set? The 6RA70 quick setup method will be briefly described below:
