Product Description:
The Danfoss frequency converter drive 175Z4159 possess the specification code VLT5032PT5C54STR3DLF00A00C0 and supports a 380V to 500V, 3-phase rated input voltage. It is capable of handling a typical shaft output of 32 kW and it offers 44 A of output current at 160% overload for a duration of 60 s, while at 110% overload the output current is measured as 61 A.
The 175Z4159 drive delivers efficient energy use with up to 0.96 and it provides 150% motor starting torque for smooth starts and is capable of 160% overload torque capability for up to 60 s. It is equipped with pre-fuse that is rated as 80 A for the line input. This drive can operate in ambient temperatures from -10°C to +50°C and the maximum cable cross-section for power supply connections is 35 mm², for motor and load sharing cables the maximum cross-section is 10 mm², while for communication lines it is 1.5 mm². It input current is rated as 60 A at 380 V supply and 53 A at 460 V. The 175Z4159 drive’s pulse width modulation (PWM) provides precise control of motor speed and torque.
The 175Z4159 drive possess 768 W power loss at high overload torque of 160% and 1065 W at normal overload torque of 110%. It is presented in both IP20 and IP54 enclosure ratings with 28 kg and 54 kg weights, respectively. The drive offers 1:100 of synchronous speed control range in open loop and 1:1000 in close loop systems. It maintains output frequency accuracy of ±0.003 Hz and delivers speed control accuracy of ±1.5 RPM at speeds below 1500 RPM. The unit works up to 1000 m of altitude and tolerates 85% RH.
Frequently Asked Questions about 175Z4159:
Q: How does the PWM (Pulse Width Modulation) in 175Z4159 improve motor control?
A: The PWM allows the converter to vary voltage and frequency precisely, reducing torque ripple and improving dynamic response. It results in more efficient motor torque delivery especially at low speeds.
Q: Why is the 1:1000 control range in closed loop significant for the 175Z4159?
A: It enables extremely fine speed regulation in feedback systems, which ensures stable operation under varying loads. This wide range improves process control critical in applications like CNC or winding machines.
Q: What purpose does the 150% starting torque serve in the 175Z4159?
A: It ensures that heavy loads or high inertia systems can be started without external means like gearboxes. This capability reduces mechanical stress and improves system startup reliability.
Q: Why is the pre-fuse rated at 80 A important for the 175Z4159?
A: The 80 A pre-fuse protects the drive from input overcurrent and short circuits, helping prevent damage to internal power electronics. It ensures safety compliance for mains connection.
Q: How does the overload current specification (160% for 60s vs 110%) affect operation of 175Z4159?
A: It allows temporary heavy loading without tripping during startup or peak loads. The 175Z4159 can sustain higher current for defined periods, preventing unnecessary shutdowns.
