Terminal B7 can also be configured as a thermistor input or frequency input. Refer to the
Commander SK Advanced User Guide for more information
If the enable terminal is opened, the drive’s output is disabled and the motor will coast to
a stop. The drive will not re-enable for 1.0s after the enable terminal is closed again.
* Following a drive trip, opening and closing the enable terminal will reset the drive. If
the run forward or run reverse terminal is closed, the drive will run straight away.
** Following a drive trip and a reset via the stop/reset key, the enable, run forward or run
reverse terminals will need to be opened and closed to allow the drive to run. This
ensures that the drive does not run when the stop/reset key is pressed.
The enable, run forward and run reverse terminals are level triggered apart from after a
trip where they become edge triggered. See * and ** above.
If the enable and run forward or enable and run reverse terminals are closed when the
drive is powered up, the drive will run straight away up to a set speed.
If both the run forward and run reverse terminals are closed, the drive will stop under the
control of the ramp and stopping modes set in Pr 30 and Pr 31.
A flyback diode should be installed across inductive loads connected to the status
relay.
B1
Analog voltage output - Motor speed
Voltage output 0 to +10V
Scaling
0V represents 0Hz/rpm output
+10V represents the value in Pr 02 Maximum set speed
Maximum output current 5mA
Resolution 0.1%
B2
+24V output
Maximum output current 100mA
B3
Digital output - Zero speed (or digital input)
Voltage range 0 to +24V
Maximum output current 50mA at +24V (current source)
The total available current from the digital output plus the +24V output is 100mA.
Terminal B3 can also be configured as a digital input, frequency output or PWM output.
