S/N - 14097
at 200 rpm 10 hz
09 - 1 accel time in 0.1 units
10 - 1 decel time in 0.1 units
14 - 230 auto torque compensation gain in 0.1% units
15 - 230 auto slip compensation gain in 0.1% units
Set P0-009 and 010 to 1.5 .1 is impossible to accelerate that fast.
Set P0-014 and 015 to 100
I also have question about these other parameters
9 and 10 are probably wrong the motor can't possibly meet a 0.1 second acceleration time. However the values in my manual are even worst at 0.5!
0.1 is impossible- 0.5 is better, but still touchy- use 1.5 These values are acceleration to max in seconds, so the larger the number, the slower the acceleration.
12 - 50 Voltage/Freq curve the manual shows a table from values from 1 to 6, I have a 50 set there but since the motor nameplate shows 60hz the number should be 4 or 5, not 50.
Nowforever changed their software in this setting and now your only choices are 50 or 60- since your motors are 60Hz, set this one to 60
14 and 15 I'm not sure if the units are really like the manual says, which would be a 23% torque gain, or is it a 230% torque gain? I'm guessing that it is a 230% gain because if I monitor the current output of the VFD without any machining loads the current about doubles when I drop the RPM to 200 vs 1000.
Yes, this is a torque boost for low rpm
Also it seems that the Gecko drive doesn't put out a linear 0 to 10v for motor speed and the rpm selection is a little off. I have read that it doesn't put out 10v when the max rpm is selected. According the the VFD manual I could probably fix this by raising the max VFD frequency because the 10V will never happen that max will never happen and the rpm will be more correct. I tried using Mach3 PID but the motor is isn't sable in lower rpms and hunts around. At higher RPMs the PID works fine.
Go back to the default PID settings in Mach 3, you can find screen shots of all settings on our web site under SPECS AND TECHNICAL BULLETINS.
The momentary rpm over-run is a function of the Nowforever which puts out 12.8 volts and the Gecko asks for only 10 volts. So for a second the rpm will overshoot due to the higher voltage until Mach 3 counts the pulses from the spindle sensor and adjusts the voltage down to the correct amount. There is an easy fix for this with a voltage regulator unit that wires into the circuit- cost is under 1.00.
