GUIDE TO THE
REGENERATIVE APPLICATION
SINUS PENTA
37/
150
Wiring for the regenerative drive powering a SINUS PENTA drive is shown in the wiring diagram above.
For the RGN application, the following analog and digital inputs/outputs are required:
Terminal
N.
Type of
I/O
Function
5
– 6
AIN1
Analog input for Vrs line voltage measured through the interface panel
7
– 8
AIN2
Analog input for Vst line voltage measured through the interface panel
17
MDI4
Digital input for bypass contactor auxiliary contact closure
AUX TL1
18
MDI5
Digital input for the state of the auxiliary contact in capacitor safety switch
AUX FCCB
30
– 31
MDO3
NO relay output for bypass contactor coil command
COIL
33
– 34
MDO4
NO relay output for regenerative drive “ON” to be series-connected to the motor-drive
enable process
To operate the regenerative drive, the ENABLE-A and ENABLE-B inputs must be enabled; in case of an
alarm, the locked condition can be reset by activating the RESET (MDI3) input.
CAUTION
Make sure that voltage and current in the coil of TL1 do not exceed MDO3-NO
contact ratings. If need be, install an additional external relay having greater
current ratings.
CAUTION
As shown in the wiring diagram, activate the MDO4-NO contact in the motor
drive enabling chain to prevent this from starting when the regenerative drive is
inactive.
