Selection and Use of the MCTC-PG Card for Monarch 3000 New System

The following table defines the CN1 terminals of different MCTC-PG card models.

3. Precautions on Connecting the MCTC-PG Card

• The cable from the MCTC-PG card to the encoder must be separated from the cables of the control circuit and the power circuit. Parallel cabling in the close distance is forbidden.
• The cable from the MCTC-PG card to the encoder must be a shielded cable. The shield must be connected to the PE on the controller side. To minimize interference, single-end grounding is suggested.
• The cable from the MCTC-PG card to the encoder must run through the duct separately and the metal shell is reliably grounded.

4. Selection of Adaptable Motor

The main counters of the electrical relationship between the controller and the motor are voltage and current.

• In general elevator applications, the input mains voltage is 380 V, and the motor voltage can only be equal to or smaller than 380 V. Thus when selecting the NICE3000 New, you can take only the current of the motor into consideration.
• When the NICE3000 New is designed, a large safety allowance is reserved for the main power module. The controller can run properly within 1.1 times of the nominal output current. During stable running, the maximum output torque is 150% of the rated torque and can reach up to 200% of the rated torque for a short time.

Therefore, for the motor with the rated voltage of 380 V, you can select the controller of the same power class. As long as the rated current of the motor is smaller than 1.1 times the output current of the controller, the controller of the same power class can also be used.
Generally speaking, when selecting an adaptable motor, ensure that the rated current of the motor is equal to or smaller than the output current of the controller.
