Pin #/
Short Form Function Remarks
1
AOK Amplifier OK “Amplifier OK” indication output pin. When
the amplifier is at normal operating
conditions, this output is in “active low “ state.
When a failure occurs, this output is changed
to “open” state. Opto isolated, open collector
NPN type, see Figure 1.
•
Maximum voltage = 30 V
• Maximum current = 8 mA
• “On” voltage: V OUT(On) < 0.8 V

3.6.2. Connecting a Non-isolated Flute to an Isolating Power
Transformer
Be sure to ground:
• DC power common
• Motor chassis
• Amplifier heatsink
Do not ground the control common, which is internally connected to the power common.
Grounding the control common will create a ground loop.
