Electrical installationClassic P3 60-150 A 01/2018 - V1 14Actual value connection4.5 Actual value connectionThe actual value is connected to the control electronics (e.g. REG) as tacho signal or as armaturevoltage signal.The quality of the actual value signal determines the control range and the control accuracy. Bestresults can be achieved through the use of dc tacho generators.Three-phase tacho generators with rotor position evaluation or digital actual value encoders aswell as ac or three-phase tachos with rectification are suitable for 1 quadrant operation.Tacho lines should be properly shielded and routed separately from power lines.Shield to be connected to the device.Please observe the tacho adjustment instructions described in the manual for the controlelectronics (e.g. REG).Manuals-Zeichnungen-P3-A054-Tachoreg.
