Figure 16 shows the location of the E-Stop terminal block (and E-Stop
configuration jumper) on the interface board.
Figure 16.
E-Stop Location
If you enable the E-Stop option, you must apply a 115 VAC signal to pins
1 and 3 in addition to the normal nuDrive enable (ENABLE switch or I/O
connector enable input, if applicable) for the nuDrive’s amplifiers/drivers
to be enabled (not inhibited). If you disconnect the 115 VAC with the
E-Stop option selected, the amplifiers/drivers are immediately disabled
(inhibited) regardless of the status of the ENABLE switch or enable input.
Refer to Figure 17 for more information on the E-Stop terminal block pin
assignment.
Figure 17.
E-Stop Terminal Block Pin Assignment
Note
The front panel ENABLE switch will remain illuminated even when the 115 VAC
signal is removed from the E-Stop connector, disabling the axes.
Servo Amplifier Configurations
The servo nuDrive uses high-efficiency PWM amplifiers configured as
torque blocks (current amplifiers or transconductance amplifiers). The
current gain is given in amps/volt and defines the relationship of the input
command voltage to the current output. The peak current limit is the
maximum current that your motor can withstand for short periods of time.
The continuous current limit is the maximum current that your motor can
withstand indefinitely.
