MSM4ARP: 4 Amp 2 HP 480V Smart Move VFD With Regen Resistors and Brake Contactor

MSM4ARP: 4 Amp 2 HP 480V Smart Move VFD With Regen Resistors and Brake Contactor

The Micro-Speed Smart-Move Variable Frequency Drives are the most compact series of VFD’s offered by Power Electronics. They have built-in internal braking resistors for travel motions.  

This series is ideal for heavy duty applications in which precise motor speed control is a requirement, such as hoists, bridge cranes, monorails, and trolleys. 

Smart Move drives are available in 3 different models, the MSM-R, MSM-RH and MSM-RP. The MSM4ARP can accommodate 300% over-current, has a 50 Deg C temperature rating with 3 speed set points. This model is PE-Preset for travel motion. There is a controlled ramp-to-top deceleration that saves you both time and money by eliminating brake wear.

MSM4ARP Series Specifications 

High Surge: Up to 300% of rated load (FLA). Best in Class! 

Dynamic Brake Circuit: All drives have internal dynamic braking regeneration resistors built into the unit! (CMAA D rated). Best in Class! 

Universal Auto-Detect™:  Automatically detects input voltage and switches between 230 V and 460 V which reduces the number of models needed to stock. 

AC Voltages: 208-230, 385-415, 460 ±10%; 480 +10% or -15%; 575 +10% or -15%. 

Hp (kW) Rating: Rating Model size range fractional through 3 Hp (.5-2.2 kW) at 460 V (see model listing). 

Frequency: Input 50 or 60 Hz ±10% nominal (others available). 

Control Type: Fully digital three-phase PWM variable frequency. 

Output Hz: 0.1 to 120 Hz standard (others on request). 

Speed Range: Up to 40:1 

Speed Controls: Up to three distinct adjustable speeds and infinitely variable control. Set speeds from 0.1 to 120 Hz (extended Hz version available). By using the two and three position infinitely variable speed control setting the machine operator can select any intermediate speed between high and low speeds. Use any two or three position pushbutton station or radio/IR control. 

Setting Method: Gang-Set® programming allows for the instant setting of different crane/hoist types. Hold three buttons down, select a Gang-Set® number and instantly set complete drive settings for many standard crane/hoist processes in seconds. Also, over 50 individually adjustable parameters are available for almost any industrial application. 

Solid-State Line VAC Brake Board (RP™): Drives are equipped with a two-pole line voltage rated solid-state AC brake controller. No external brake contactor may be required for horizontal travel motion. Available on RP™ models only. 

DC Injection Braking: DC power is injected into the motor winding near the stopping speed point. Effectively stops the motor without wearing mechanical holding brakes. Also works great on motions which do not require brakes! 

Programmable Relay: High-reliability auxiliary Form C relay with user programmability. 

Motor Overload Circuit Protection: Thermal inputs, electromechanical overload input, internal programmable I²T, Ground fault 

Voltage Protection: Overvoltage and undervoltage bus trips. 

DC Bus Indicator: LED on until DC bus voltage drops below 50 VDC. 

Available Conformal Coating: Safeguard electronics from corrosive gases, liquids and excessive moisture (optional). 

Enclosure: Powder coated steel (not plastic) for increased EMI protection, and higher resistance to atypical shock and vibration. 

Humidity: Non-condensing 

Limit Switch Inputs: Left and right optically isolated limit switch inputs. Programmable slowdown and stop. 

Optically Isolated Speed Inputs: F (forward), R (reverse), S2 (second speed) through S5 (fifth speed); 115 VAC standard, others available. Standard control inputs are optically isolated. No external input cards necessary (115 VAC standard, 24 VAC, and others available by request).
