1V2450

Product Description

The 1V2450 drive is a 1HP AC drive from Reliance Electric's GV3000 series of drives. A cabinet-based drive, the 1V2450 model drive flaunts a NEMA 4x/12-type enclosure and a relatively muted input voltage rating of 200-230 VAC, for less high-powered automation needs. Similarly to MANY of the GV3000 series from Reliance, this drive has a Hz rating of 50Hz and produces a kilo wattage score of 0.75kW. A PWM or pulse-width-modulated drive, the 1V2450 offers dual regulation types in both vector and general regulation. The 1V2450 drive is a standard-sized GV3000 series drive at 16x16x16, and the weight of the drive sits at a solid ten pounds.

The versatility of the 1V2450 drive is only matched by its' solid voltage protection and insulation. This particular drive offers crucial features such as overload protection and short-circuit detection, decreasing the likelihood of faults such as:

• the overcurrent at DC braking fault (fault code OCb),
•  motor overload fault (fault code OL),
• the drive power electronic overload fault (PUo),
• and many more!

While the advanced surge protection and electrical work done on the 1V2450 GV3000 drive helps to avoid several relevant faults, other faults that may possibly inconvenience the 1V2450 drive owner are more than worth mentioning. A primary fault that one might manage to encounter with this GV3000-series drive is the overfrequency fault, represented on the drive's built-in keypad display as OF. This fault is oftentimes caused by the drive exceeding the maximum allowable output frequency, causing an excessive regenerating energy. In this fault's case, the drive's stability or slip compensation circuit may add frequency reference. If the drive's H.016 is ON, the searching current is too high, and the motor is too small. Corrective action for the OF fault would be to check the vector parameters of PPR, motor poles, and base frequency. If the issue is not found within the vector parameters, then checks on the V/Hz parameters of maximum speed, overfrequency, and slip compensation may be required. If the fault has not been identified within these stated parameters, then check the DC voltage, check the P.005 setting, increase 1V2450's deceleration time, and check the motor size relative to the power module.
