PMAC Product Guide Note: The DAC screen of the EZ-PMAC Setup Software allows changing the state of the amplifier enable signal which could then be measured with a voltmeter. Fail safe indicates that the output chip must be operating properly for the amplifier enable output to enable the amplifier. Other configurations might still enable the amplifier even if the output chip is damaged or not operating properly. Amplifier Fault Signal (FAULTn) This input can take a signal from the amplifier so PMAC knows when the amplifier is having problems and can shut down action. The polarity is programmable with I-Variable Ix25 (I125 for motor #1) and the return signal is analog ground (AGND).
FAULT1 is pin 49. With the default setup, this signal must actively be pulled low for a fault condition. In this setup, if nothing is wired into this input, PMAC will consider the motor not to be in a fault condition. Note: The Flags screen of the EZ-PMAC Setup Software allows the setup and monitoring the state of the amplifier fault signal. 32 Machine Connections Amplifier Enable Jumpers - Summary Table Amplifier Enables with … PMAC Jumper Configuration Output Chip (U54) AGND (fail safe) E17: OFF E100: 1-2 E101: 1-2 E102: 1-2 ULN2803A (default) 12-15V E17: ON E100: 1-2 E101: 1-2 E102: 1-2 ULN2803A (default) 12-15V (fail safe) E17: OFF E100: 1-2 E101: 2-3 E102:
