Product Description:
The 175Z4135 Frequency Converter provides both digital and analog outputs that ensures flexibility in industrial automation. The unit is equipped with programmable outputs that allows adaptation to multiple control environments.
The 175Z4135 frequency converter from Danfoss includes two programmable digital and analog outputs that are located on terminals 42 and 45. The digital or pulse output operates within a voltage range of 0 to 24 V DC. To ensure reliable operation, it requires a minimum load of 600 ohms connected to ground at terminal 39. The digital output when configured for pulse functionality supports frequency ranges from 0 to 32 kHz. The analog output operates in a current range of either 0 to 20 mA which allows seamless integration with various measurement and monitoring systems. The analog output is capable of handling a maximum load of 500 ohms to ground at terminal 39. The accuracy of the analog output is maintained within a maximum error of 1.5 % of full scale that ensures precise signal performance. The resolution on the analog output is 8 bit that supports consistent monitoring and control. The motor phase monitoring is built in on this converter and linked to parameter 234 which helps detect and shut down on phase loss. If there is a mains fault, the drive supports controlled deramping.
The 175Z4135 frequency converter provides motor current measurements ranging from 0 to 140 % load with a maximum error of ± 2.0 % of the rated output current for display readout parameters. The torque measurement ranges from - 100 to 140 % load with a maximum error of ± 5 % of rated motor size. These specifications ensure accurate and reliable motor monitoring in demanding applications.
Frequently Asked Questions about 175Z4135:
Q: What analog signal characteristics make the 175Z4135 frequency converter compatible with external monitoring systems?
A: It delivers a current output up to 20 mA with 8-bit resolution and 1.5% accuracy. The output can handle 500-ohm loads, enabling stable data flow to analog input devices.
Q: How does the 175Z4135 frequency converter handle dual-function output requirements in hybrid control systems?
A: It provides two programmable outputs on terminals 42 and 45 that can function as digital or analog. This supports seamless adaptation to pulse-based or current-loop automation tasks.
Q: What role does the 175Z4135 frequency converter play in early detection of motor phase issues?
A: Motor phase monitoring is built in and linked to parameter 234. It helps detect phase loss and initiates shutdown to protect the motor from asymmetrical loading.
Q: How accurate are torque and current measurements during dynamic motor operation with the 175Z4135 frequency converter?
A: Torque is measured from -100% to 140% with a ±5% error margin, while current has ±2% accuracy up to 140% load. These metrics support diagnostics during high variability in load.
Q: How does the 175Z4135 frequency converter ensure safe motor shutdown during mains power faults?
A: It supports controlled deramping in response to mains failure. This controlled deceleration minimizes mechanical stress and prevents abrupt process interruptions.
