7.5 - IP 20 braking resistor
(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).

External resistors with greater thermal power can be used,
provided that the minimum ohmic value of 180 W (RF 100 –
RF 200) or 50 W (RF 600) is respected.

OPTIONS
7.7 - Power supply and sequential brake
control (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.
7.8 - Power supply and sequential brake
control (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.
