2.7.2.2 Description of Terminal :1/:25 DC +24 V
terminal strip Potential-free and short-circuit resistant voltage
inputs / outputs source to supply the standard terminal strip.
Terminal :2/:26 DC 0 V
Reference potential for +24 V terminal :1/:25
Terminal :3/:4 PTC MOTOR-TEMP
Connection for motor thermistor resistor for motor temperature
monitoring.If the processing electronics respond, “Motor
overtemperature” is signalled. The inverter shuts down with the
error message “Motor overtemperature”. If no motor thermistor
resistor is connected, terminals :3 and :4 are to be bridged.
Terminal :5 ON/STOP
The inverter is switched on by the rising flank of the +24 V signal.
When the link has been precharged the internal main contactor
(DC) is energised. The inverter is shut down and the drive brought
to a controlled standstill at LOW level. With the drive at a standstill
the pulses are disabled, the main contactor (DC) is de-energised
and the link is discharged (if a brake chopper is fitted). De-
energisation of the internal main contactor and link discharge can
be prevented by appropriate parameter settings (see section
4.4.3.).
After an error is acknowledged, a new rising flank is required for
starting.
If automatic restarting is selected, within the specified restart time
no rising flank is required after the mains voltage returns if the
ON/STOP signal is still HIGH.
Terminal :6 MANUAL/AUTOMATIC
Manual/Automatic changeover
LOW corresponds to manual and HIGH corresponds to automatic
operation. The signal source controlling the inverter can be
switched with this terminal. The source for manual or automatic
operation is parameter-adjustable and can be set to terminal strip,
control unit, PC serial interface, field bus 1, field bus 2.
Standard setting: Manual = Control unit
Automatic = Terminal strip
Manual/automatic changeover is only possible from the terminal
strip.
Terminal :7 STOP
A flank from HIGH to LOW results in the drive being brought to a
controlled standstill at the braking ramp. On standstill, the pulses
are disabled and the main contactor (DC) is de-energised. This
signal takes effect from the sources terminal strip, BDE, serial
interface and field bus. The stop function via the BDE control unit
can be disabled using the handling software parameters.
