required supply voltage.

4.1.2 Normal Operation for Trolley

The inverter goes into Ready-to-Run within one second after power is applied to the inverter. During running,

the inverter follows the user defined speed control mode.

The default speed control mode is the two-speed (MS-2).

The stopping method, which the user cannot change on TMU VFD, is programmed to decelerate to a stop

using dynamic braking. As a result of this, the brake is used essentially as a holding brake and the wear on

the brake is minimized. When the RUN Forward/Reverse command is removed, the inverter decelerates to

zero according to its preset ramp time and then the brake sets. If a failure occurs or if the emergency stop

button is pushed, dynamic braking is overridden and the brake closes immediately, bringing the motor and

load to an immediate stop.

4.1.3 LED Status Indicator

TMU VFD indicates its operating status by two LEDs. A steady green LED indicates Ready-to-Run. A

blinking green LED indicates that a fault condition had been activated, but the fault has since recovered.

Normal operation is possible when the green LED is blinking. A blinking red LED indicates a severe fault

condition and operation is inhibited. The blinking pattern tells the user the type of fault that has occurred.
