    7 - THEORY OF OPERATION 7.5.9 DC Injection Braking Parameters The DC Brake Level parameter sets the level of DC current applied to the motor during braking. The desired Brake Level: brake level is determined by the combination of the system inertia, system friction, and the desired braking time.

When set to Slow Speed: "Off", slow speed operation is disabled. Slow Speed Current Level: The Slow Speed Current Level parameter selects the level of current applied to the motor during slow speed operation.

    7 - THEORY OF OPERATION Inside Delta Connected Starter Inside Delta Connected Starter There are differences between a line connected soft starter as shown in Figure 49 and the inside delta connected soft starter as shown in Figure 50 that need to be considered. By observation of Figure 50, access to all six stator-winding terminals is required for an inside delta application.

  • Page 175: Inside Delta Connected Starter

    7 - THEORY OF OPERATION 7.7.2 Inside Delta Connected Starter An inside delta connected soft starter is shown in Figure 50, where the power poles are connected in series with the stator windings of a delta connected motor. Figure 50: Typical Inside Delta Motor Connection NOTE: Current Transformers MUST be installed to measure the full line current and never installed so they measure the current inside the delta connection.

  • Page 176: Wye Delta Starter

    7 - THEORY OF OPERATION Wye Delta Starter Wye Delta Starter When the Starter Type parameter is set to Wye-Delta, the MX is configured to operate an electro mechanical Wye-Delta (Star-Delta) starter. When in Wye-Delta mode, all MX motor and starter protective functions except bad SCR detection and power stack overload, are available to provide full motor and starter protection.
  • Page 177 7 - THEORY OF OPERATION The MX utilizes an intelligent Wye to Delta transition algorithm. During starting, if the measured motor current drops below 85% of FLA and more than 25% of the Up To Speed timer setting has elapsed, then a Wye to Delta transition occurs. The intelligent transition algorithm prevents unnecessarily long motor starts which reduces motor heating.
  • Page 178 7 - THEORY OF OPERATION Usually the MX intelligent Wye to Delta transition algorithm provides an optimal transition point that minimizes the transient current and torque surges that can occur. However, the Wye to Delta transition will occur when the Up To Speed Time parameter has expired. In order to reduce the current surge during the transition from Wye to Delta mode, the Up To Speed Time parameter should be adjusted so that the transition occurs as close to full speed as possible within the constraints of the load.

  • Page 179: Across The Line (Full Voltage Starter)

    7 - THEORY OF OPERATION Across The Line Starter Across The Line (Full Voltage Starter) When the Starter Type parameter is set to ATL, the MX is configured to operate an electro mechanical full voltage or across-the-line (ATL) starter. In the ATL configuration, the MX assumes that the motor contactor (1M) is directly controlled by an output relay that is programmed to RUN.

    7 - THEORY OF OPERATION Single Phase Soft Starter 7.10 Single Phase Soft Starter There are times a single phase motor may need to be started using a soft starter. This can be accomplished with any 3 phase starter with the following modifications to the starter.

  • Page 181: Phase Control

    7 - THEORY OF OPERATION Phase Control 7.11 Phase Control When the Starter Type parameter (FUN07) is set to Phase Control, the MX is configured to operate as a phase controller or voltage follower. This is an open loop control mode. When a start command is given, the RUN programmed relays energize. The firing angles of the SCRs are directly controlled based on voltage or current applied to the Analog Input.

  • Page 182: Phase Controller

    7 - THEORY OF OPERATION 7.11.1 Phase Controller: Phase control can be used to directly control the voltage applied to motors, resistive heaters, etc. When in Phase Control mode, the phase angle of the SCRs, and hence the voltage applied, is directly controlled based on the analog input signal. The MX reference command can be generated from any 0-10V, 0-20mA or similar source, such as a potentiometer, another MX or an external controller such as a...

    7 - THEORY OF OPERATION Current Follower 7.12 Current Follower When the Starter Type parameter (FUN 07) is set to Current Follower, the MX is configured to operate as a Closed Loop current follower. Current Follower mode can be used to control the current applied to motors, resistive heaters, etc. The Current Follower mode uses the analog input to receive the desired current command and controls the SCRs to output the commanded current.
