VFD 220V 2.2KW 3HP 9.6A 220V Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

I own three of these VFDs, and they have had 0 issues. The manual isn't bad at all, either. I was able to program this and understand the advanced settings very easily. Look, I'm not even running any circuit protection yet, and they work Flawlessly. I couldn't recommend the Mollom VFDs enough. Their price point and quality are spot on. I am not doing production work, I have a hobby shop with larger equipment.!

For the price, this is amazing. I initially had it set up with the included remote panel, but now have a variable resistor for speed and push buttons for forward and reverse. Running a 2hp lathe. Great fine control once I got the settings dialed in.

I'm using this to get a Boss3 mill running with LinuxCNC. I'm able to get it to run the spindle manually (using the panel), and just today I was able to get the computer to make it run over RS-485. The documentation leaves out the setting for the baud rate. FD-00 -> 0:300, 1:600, 2:1200, 3:2400, 4:4800, 5:9600, 6:19200, 7:38400, 8:57600, 9:115200Also not documented: 1000H sets the speed. You wire a value between 0 an d10,000 to get between 0% and 100% of the speed range set by the MaxLow and MaxHigh frequency registers.The device only implements commands 3 (read a single register) and 6 (write a single register) of the protocol (unless there is more of the documentation that is missing).As stated above. I've been able to get it to run the spindle over RS-485. I've also been able to get it to run in reverse. Sending 1 or 2 to address 2000H, respectively. Initially, I was unable to get it to stop. Once I ran the communication wires through a ferrite bead (I made two loops), It worked find.I've not yet worked on reading the status registers.My configuration file for mb2hal in LinuxCNC is:# ++++++++++++++++++++++++# Common section# ++++++++++++++++++++++++[MB2HAL_INIT]INIT_DEBUG=3SLOWDOWN=0.0TOTAL_TRANSACTIONS=3# ++++++++++++++++++++++++# Transactions# ++++++++++++++++++++++++[TRANSACTION_00]LINK_TYPE=serialSERIAL_PORT=/dev/ttyACM0SERIAL_BAUD=9600SERIAL_BITS=8SERIAL_PARITY=noneSERIAL_STOP=2SERIAL_DELAY_MS=20MB_SLAVE_ID=1FIRST_ELEMENT=8192PIN_NAMES=target_stateMB_TX_CODE=fnct_06_write_single_registerMB_RESPONSE_TIMEOUT_MS=500MB_BYTE_TIMEOUT_MS=500HAL_TX_NAME=spindle_setMAX_UPDATE_RATE=0.0[TRANSACTION_01]FIRST_ELEMENT=4096PIN_NAMES=target_speedMB_TX_CODE=fnct_06_write_single_registerHAL_TX_NAME=spindle_speed[TRANSACTION_02]FIRST_ELEMENT=12288PIN_NAMES=current_stateMB_TX_CODE=fnct_03_read_holding_registersHAL_TX_NAME=spindle_read

Un like the Rufus report suggested an engineer friend and I spent 4 hours trying to understand the grossly inadequate manual. It finally came down top three settings that were inter-related in an incomprehensible way. The three settings were so odd that we finally did an eight way transform of all three to discover which combination could work at all.That said, the device is marvelous. My Powermatic lathe is stronger than that same friend's brand new Powermatic lathe.Fix the manual!

Swapped out the 1.5 HP 1 phase motor with a 2hp, 3-phase motor on my knee mill. The manual was well written, making it esy to set it up. I added a remote RUN switch and remote speed control. I was alble to tune the VFD to reduce the hum. The VFD works great. I like the dual diaplay, showing both frequency and motor amps,

This worked great to allow my 3 phase compressor motor to use 1 phase power. It also helps limit the current inrush, and start and stop rates. Very cool product.

Cumple perfectamente con sus funciones...muy recomendable...

This drive has been running my bench top mill for almost one year. More than half the time after pushing the stop button the motor does not stop. It will slow down and ramp up on its own, but won’t stop. When it does this the only way to make it stop is to turn off the breaker feeding the drive.Requested a replacement multiple times to no avail. The experience with customer service was akin to running in circles.Not impressed.
