SECTION 3. INSTALLATION 13
Pin 4 is drive ground and is linked to mains earth via a high frequency filter.
Pin 5 Reset
Pin 5 is the reset input, when the input is low, the drive is de-energised. Any latched faults
remain latched while the input is low and are reset on the high-going edge.
The reset input can be configured by bit switch 6. If bit switch 6 is OFF and the reset input is
open circuit, this input is pulled down to 0V via a 15k ohms resistor and the drive is de-energised.
To energised the drive, the reset input must be connected to +15V (pin 6 of the the user I/O
connector) via a switch or a PNP transistor.
Note: this is the 'fail safe' configuration.
Note: When bit switch 6 is OFF a connection must be made between pins 5 and 6 of the
Drive I/O connector to enable the drive.
If bit switch 6 is ON and the reset input is open circuit, the reset input is pulled up to +15V using
a 15k ohm resistor and the drive is energised. To de-energise the drive you will need to connect
this input to 0V (pin 4 of the user I/O connector).
Pin 7 Tach Output
Pin 7 is the internally buffered tachometer output. The output produces a signal of approximately
2V/krpm independent of line count. The output polarity is positive for CW motor rotation. This
output is not intended for accurate speed calibration, but for use when setting up the drive.
Pin 8 Current Monitor
Pin 8 is a unipolar current monitor signal used to indicate the total motor current with a sensitivity
of 2A/V for the BD150 (1A/V for the BD75). This output is not intended for accurate current
calibration, but for use when setting up the drive.
Note: the output represents a rectified summation of the 3 actual motor phase currents
thus, even when delivering a constant torque, the signal will contain approximately 13%
ripple at low shaft speeds.
