Cable Length for Each Parallel Cable, Depending on Quantity of Parallel Cables.Problems may arise at start and at low RPM values if motor sizes are widely different because small motors' relatively highohmic resistance in the stator calls for a higher voltage at start and at low RPM values.The electronic thermal relay (ETR) of the adjustable frequency drive cannot be used as motor protection for the individualmotor of systems with parallel-connected motors. Provide further motor protection with, for example, thermistors in eachmotor or individual thermal relays (Circuit breakers are not suitable as protection).6.4.4 Direction of Motor RotationThe default setting is clockwise rotation with the adjustable frequency drive output connected as follows.Terminal 96 connected to U-phaseTerminal 97 connected to V-phaseTerminal 98 connected to W-phaseThe direction of motor rotation is changed by switching two motor phases.Motor rotation check can be performed using 1-28 Motor Rotation Check and following the steps shown in the display.Electrical Installation Design Guide118 Danfoss A/S © Rev. 06/2014 All rights reserved.
