Fadal - AC Brushless Amplifier, Linear Way - AMP-0039

SKU: AMP-0039
(0)
$2,032.00 CAD

The AMP-0039 is the Glentek AC brushless amplifier used on linear-way Fadal VMCs running 5000 line motors. One card per axis, X, Y, Z, A, or B. When an axis stalls, chatters, or won't hold position on these smaller-frame machines, this is the amplifier most likely at fault.

Specifications ▼

Output Current

10A continuous, 20A peak

Encoder Line Count

5000 line, AC brushless, drives a 6-pole motor

Motor Compatibility

Glentek MTR-0139, Baldor MTR-0141

Overload Protection

Current and temperature sensors built in. Folds back to continuous output after 3 seconds at peak rather than shutting down outright.

Fault Codes ▼

Fault Code 1

"No motor feedback" appears on power up if no motor feedback (resolver or encoder) or no motor motion is detected by the axis controller.

Fault Code 18

"Servo amplifier fault line down" the axis card no longer detects the fault line signal from the amplifier, or the signal strength drops below 10V.

Compatible Machines ▼

Fadal VMC 3016 and other linear-way VMCs, 1997 or newer

Axes covered: X, Y, Z, A, B. XYZ motors are square-frame; rotary motors are round-frame. Confirm your motor type before ordering.

Test Before You Swap

Measure the three motor wires (R, S, T) to ground before replacing the amplifier, each should read 1–10 megaohms. A shorted motor can damage a good amplifier on installation, so rule out the motor first.

Post-Install Adjustment

Three potentiometers need adjustment after install; compensation, signal gain, and balance, to dynamically balance the amp against the other axes. Target following error: 302 for metric ballscrews, 595 for inch ballscrews.

VMC15 / VMC2016L Owners

Whether your machine uses this amplifier family depends on production year. Submit an RFQ with your motor part number to confirm before ordering.

Also Needed For This Job

If all three axes on the same chassis are failing, you may need the full AMP-0038 chassis assembly instead. If the amplifier tests fine but the axis still misbehaves, the motor itself (MTR-0139 or MTR-0141) may be the actual failure point.
