VMX-62-BP-240 - Motortronics

Multiple Ramp Types to Start any Load

Closed Loop Current Ramp or Voltage Ramp, with or without Current Limit

Built-in Decel Control, Dual Ramp, Kick Start and Jog Modes

Unit Overload Capacity (% FLA)

350% - 30 Seconds

600% - 10 Seconds

Start & Run Protection

Two programmable overload trip curves allow for the thermal capacity required to start the load while providing motor overload protection needed during the run time.

• Start: Programmable for Class 5 - 30


• Run: Programmable for Class 5 5 - 30, enabled when starter detects motor is "At-Speed"


• Reset: Manual or automatic, selectable via programming. Remote reset available.

Real-Time Thermal Modeling

Continuously calculates motor operating temperature even when the motor is not running.

Retentive Thermal Memory

Remembers the thermal condition of the motor even in the event of a power brown-out or black-out when power is restored.

Extrapolates motor temperature using a real-time clock.

Dynamic Reset Capacity

Overload will not reset until thermal capacity in the motor is sufficient for a successful restart. Starter learns and retains this information from previous starts.

Control

120V AC (customer supplied),240V (optional)

24V DC dry contact inputs, no external DC power supply required

Motor Temperature

PTC thermistor input can also be used for E-stop or external overload relay.

Equipment Ground Fault

Residual current method with adjustable trip delay.

RS485 Modbus Communications

Full control and/or status monitoring over network or direct to a PC.

Phase Current Imbalance/Loss Protection

Trip level: 5 - 30% current imbalance between any two phases with trip delay.

Phase Loss

Trips on phase current or voltage loss.

Phase Rotation

Phase rotation trip can be set to A-B-C , A-C-B or disabled.

Electronic Shear Pin Protection

Trip level: 100-300% of motor FLA with trip delay.

Load Loss (Under Current) Trip Protection

Trip level: 10-90% of motor FLA with trip delay.

Phase Loss Motor Duty Cycle Protection

Back-spin/coast-down, starts-per-hour or minimum time between starts lockouts. Restart delay after a power failure.

Short Circuit

Trips at 10x unit current rating during run. Checks for shorted load prior to each start.

Shorted SCR

Locks out on any single shorted SCR (defeatable) or can provide shunt trip function if multiple SCRs short or bypass contactor is welded closed.

Metering

Monitoring phase current, ground current and motor thermal capacity.
