Page 8: Pin Assignment And Functions
MECON LVT20 SERIES 6. PIN ASSIGNMENT AND FUNCTIONS LVT20B pin assignment: C4 C5 Connector C1 Function Positive supply voltage (48 VDC). Pin1 | DC + Negative supply voltage (GND). Pin2 | DC – Motor phase A. Pin3 | PHA Motor phase B. - Page 9 Logic ‘low’: Motor starts to rotate as per the set speed and will accelerate as per the set acceleration. Logic ‘high’: Motor stops Connector C3 Function Positive supply (for external mash electric keypad). Pin1 | +5V Pin2 | +5V Pin3 | n.c RS-485 B terminal.
- Page 10 MECON LVT20 SERIES LED C4 Function Indicates the power status of the controller. GREEN LED Indicates the fault conditions of the controller. RED LED SWITCH C5 Function Resets the controller in case of ‘fault latch’ condition. Do not attempt to reset the RESET controller in normal condition or while the controller is in operation.
- Page 11 MECON LVT20 SERIES LVT20A pin assignment: Connector C1 Function Positive supply voltage (48 VDC). Pin1 | DC + Negative supply voltage (GND). Pin2 | DC – Motor phase A. Pin3 | PHA Motor phase B. Pin4 | PHB Motor phase C.
- Page 12 MECON LVT20 SERIES Pin10 | enable Logic signal to enable or disable the motor rotation. Logic ‘high’: Motor stops rotating and deccelerate as per the set deceleration. Logic ‘low’: Motor starts to rotate as per the set speed and will accelerate as per the set acceleration.

Controller parameters can be configured via RS-485 communication. MEDEval software is used to configure the parameters of the controller. For further information regarding the software refer to MEDEval QUICK GUIDE document. LVT20 series controller basic parameters: Function Range Factory Default... - Page 15 MECON LVT20 SERIES Connecting the motor for the first time. For connecting the motor, check the motors rated specification and accordingly set the controller parameters via RS-485 communication using MEDEval software. After setting the parameters, suitable to run the motor, connect the motor hall sensor wires and main DC supply wires to the controller (For now, do not connect the phase wires).
