Product Description:
The Danfoss VLT 5000 drive 175Z4131 is designed with the specification code VLT5027PT5C20EBR3D0F00A00C0. It is built for 380 to 500 V, 3-phase mains supply and it supports a supply frequency between 48 and 62 Hz. The drive’s rated output current is 44 A at 380 to 440 V and 41.4 A at 441 to 500 V, while its maximum output current for 60 seconds is specified as 48.4 A and 45.5 A at the respective voltages.
The 175Z4131 drive possess a typical motor shaft power output of 30 HP and its efficiency at rated load is 0.96. Its power factor at displacement is around 0.98 and its true power factor is approx. 0.90. The unit’s switching frequency can be selected between 2 to 12 kHz and its output frequency range is 0.2 to 1000 Hz. Its configurable ramp time setting is between 0.05 s to 3600 s and its starting torque value is 160% for 60 s and 180% for 0.5 s. This 175Z4131 drive is protected with pre-fuse rated as 60 A and its power losses at maximum load are about 768 W. its recommended cable cross section for motor and power is 6 AWG.
The 175Z4131 drive is presented in a mechanical compact dimension of 700 mm H, 242 mm W and 260 mm D. Its control inputs include eight digital inputs rated 0 to 24 V DC and three analog inputs with range of up 10 V at 0/4 to 20 mA. The drive supports encoder inputs up to 65 kHz and its outputs include two configurable analog or digital channels as well as two relays. The drive comes with both options of enclosure that are classified as IP20 or IP54, with respective weights of 27 kg and 42 kg.
Frequently Asked Questions about 175Z4131:
Q: How does a ramp time range of 0.05 s to 3600 s improve operation for the 175Z4131?
A: Its such wide ramp range allows both very fast starts/stops and very gradual acceleration/deceleration, reducing mechanical stress. It helps tailor drive behavior for application types like hoists or slow-ramp conveyors.
Q: How does the high starting torque (160 % for 60 s, 180 % for 0.5 s) in the 175Z4131 help in motor applications?
A: It allows the motor to overcome static friction or load inertia during startup without stalling. This is especially important in applications like large pumps or loads with high inertia.
Q: What role does the encoder input (up to 65 kHz) play in the Danfoss VLT 5000 drive 175Z4131?
A: The encoder input allows closed-loop feedback for precise speed and position control, enhancing performance and accuracy. It is crucial in applications requiring tight regulation, such as robotics or material handling.
Q: Why are different enclosure ratings (IP20 vs IP54) significant for the 175Z4131?
A: Its IP20 offers protection against solid objects over 12 mm but no water protection, suited for clean environments; IP54 adds protection against dust and splashing water. Choosing proper enclosure safeguards electronics and ensures compliance with environmental demands.
Q: How does the true power factor of approx. 0.90 benefit the Danfoss VLT 5000 drive (175Z4131)?
A: A high true power factor means more of the supplied power is used effectively, reducing wasted energy and lowering electric bills. It also reduces reactive current, easing demands on upstream supply and wiring.
