*If snaps can't be felt, increase current to make them stronger. | *If snaps can't be felt, increase current to make them stronger. | ||
*If motor has internal brake, it must be electrically opened before the test. Usually such brakes open with 24VDC voltage to brake wires. Check motor specifications first, or use lower starting voltage if unknown. | *If motor has internal brake, it must be electrically opened before the test.
