2.5 Speed feedback balancing
Activate EMF speed feedback:
50.03 = CALC BY EMF
Select no
field weakening mode:
15.06 = FIX
50.01 = Desired speed / or motor rating plate
Scale speed control circuit to maximum speed.
Switch ON power.
DANGER: System components now energized!
Start drive.
Increase reference value in LOCAL mode to 10 % of the maximum speed.
Drive should run up to 10 % of the rated voltage.
Continue with one of the following sections:
• Only when an analog tacho is being used!
• Only when an encoder (pulse encoder) is being used!
• Only when the EMF signal is being used as speed feedback!
Only when an analog tacho is being used!
Connect measuring instrument:
- to X3: 1... 3 or X1: 1... 3
+ to X3: 4 or X1: 4
Check to make sure that the tacho voltage does not exceed the input voltage range
selected with maximum speed.
Turn Potentiometer R2716 [on SDCS-CON-2 board] or R9 [on PS5311 board; if
SDCS-IOB-3 board is used with PS5311] to minimum (left-hand stop).The
measured value must have a positive sign; if necessary interchange tacho cables.
Stop the drive and switch OFF power!
50.03 = ANALOGUE TAC
Analog tacho is used for speed control.
Switch ON power.
DANGER: System components now energized!
