DCREG4
TERM. Description
36 MDI 5: Digital input 5 to be configured through parameter C134 (MDI5Cfg).
Default configuration: 4:Clim.
37-39 MDO 4: Digital output 4 to be configured through parameter P188 (MDO4Cfg).
Default configuration: 5:Drive Running.
Decisive voltage class C according to EN 61800-5-1
38 MDI 6: Digital input 6 to be configured through parameter C135 (MDI6Cfg).
Default configuration: 5:Reverse.
40 +24V (OPTO): +24V main voltage supply output for digital inputs operation
and/or to supply the enP/Nr. It is optoinsulated from the 0V signal of analog
inputs.
41-43 MDO 5: Digital output 5 to be configured through parameter P194 (MDO5Cfg).
Default configuration: 4:CurrLimitation.
Decisive voltage class C according to EN 61800-5-1
42 0V(OPTO): Negative terminal of +24V external supply voltage (if any) to supply
the control section and/or the enP/Nr. It is optoinsulated from the 0V signal of
analog inputs. If the digital inputs come from the static outputs of a PLC, 0V of
the PLC is to be connected to this terminal.
44 +24V(EXT): Input for positive terminal of +24V external supply voltage to supply
the control section.
Note (*)
1a DRIVE LOCK WHILE STOPPING.
Suppose C051 is set at 1:Predictive=>J1 value. In that case, even after the START contact to terminal 26
is open and the motor fall ramp is over, if the ENABLE contact to terminal 24 is kept closed, the drive
"regulates zero current" (no torque is generated), i.e. the drive is still operating, although the motor is
idling.
While the motor is not running (idling), if for some particular reasons contactor KM has to remain closed
for a long time, for the operator's safety it is possible to wire an additional contact to terminal 24; such
contact is to be series connected to auxiliary contact NO of contactor KM. If this contact opens, the current
reference will be set to zero, and the drive will be disabled (motor idling, drive in stand-by).
On the other hand, in case parameter C051 is set at 0:PI operating, the drive will automatically inhibit any
firing pulse as soon as the motor down ramp is over. The motor keeps idling.
1b MOTOR NEUTRAL
If a rotating motor controlled by the drive is to be put in neutral, the contactor is recommended not to be
opened. First open the above-mentioned additional contact (which is to be previously wired to terminal 24,
series connected to auxiliary NO contact of contactor KM), then open contactor KM.
1c CLOSING THE ENABLE CONTACT WHEN THE MOTOR IS IDLING.
When the connected motor is idling and the ENABLE contact is closed but the START contact is open, the
system sets the ramp set for par. P034 (RampStopPos) or par. P035 (RampStopNeg) up to zero speed.
The connected motor keeps idling.
