3.3 - Power terminal blocks

3.3.1 - Terminal block for power supply PB1
(marked L1, L2 and L3)
This terminal block is used to connect the 3-phase power
supply when the EMC filter is not supplied with the
VARMECA 30. Otherwise, the EMC filter output is screwed
onto this connector and the power supply should be attached
to the terminals located on top of the filter.
Screw terminal block:VMA 33/34
Tightening torque 1.8 N.m
2
Max. cross-section 4 mm
3.3.2 - Terminal block for braking resistor PB2
(marked R+ and R-)
This terminal block is used to connect a braking resistor when
this option is required. The resistor is mounted on the outside
and/or the rear of the VARMECA 30 casing.
Screw terminal block:VMA 33/34
Tightening torque 1.8 N.m
2
Max. cross-section 4 mm
Note: For the VMA 31/32, PB1 and PB2 are both
located on the same terminal block.
The terminal block on the VARMECA 31/32 has a terminal
marked FI connected to the R- terminal which enables
use of the internal braking resistor. The jumper must be
removed when an external braking resistor is connected
or if the inertia is incompatible with the rated
deceleration ramp.

CONNECTIONS

3.4 - Terminal blocks for options

3.4.1 - RS485 type serial link connector
This is an RJ 45 connector and is used to connect the PX LCD
console or a PC in order to use the PEGASE VMA 30
programming software.
For the VMA 31/32 it is also used to connect the fieldbus or the
PADVMA 31/32 option.
3.4.2 - Description of Slot 1
(VMA 33/34 only)
This slot is used to connect the encoder feedback module
(option: COD VMA 30) when "closed loop" mode is selected.
3.4.3 - Description of Slot 2
(VMA 33/34 only)
This slot is used to connect one of the fieldbus modules
(protocols supported: PROFIBUS DP, INTERBUS S,
DEVICE NET and CAN OPEN).
3.4.4 - P2 connector (VMA 31/32 only)
This is used to connect the following options: Local
potentiometer (B 31/32), local potentiometer with integrated
Run/Stop (BMA 31/32), local potentiometer with integrated
Forward/Reverse/Stop
(ESFRVMA 30), etc.
