7.5 - IP 65 braking resistor option
(RF100 – RF200 – RF600)
For operation in 4 quadrants and energy dissipation, resistors
can be fixed directly onto the VARMECA casing. In this case,
the jumper between terminals FI and R- should be
removed (VMA 31 and 32).

7.7 - Power supply and
electromechanical brake control option
(SO VMA 31/32)
The motor must be fitted with an FCR brake adapted for the
VARMECA 31/32.
The brake has a built-in power supply. The brake is released
as soon as the run command is enabled. The brake is
engaged after a stop command, at the end of the deceleration
ramp or on disconnection of the power supply.
7.8 - Additional I/O interface and
sequential brake control option
(ESFR VMA 31/32)
The brake has a built-in power supply. The brake is controlled
according to a sequence which can be adjusted using the
VARMECA parameters.
7.9 - Additional I/O interface and
sequential brake control option
(ESFR VMA 33/34)
The brake has a built-in power supply. The brake is controlled
according to a sequence which can be adjusted using the
VARMECA parameters. See VARMECA 30 parameter-
setting manual.
7.10 - Fieldbus options (not available
for VMA32 M)
The interface card is mounted inside the VARMECA casing.
Protocols supported:
PROFIBUS DP - INTERBUS S
DEVICENET - CAN OPEN
7.11 - Encoder feedback option
(COD VMA 33/34)
VMA33/34 only: Please contact Leroy-Somer.
