Réf. 3195 - 4.33/d - 12.99
7.5 - Integrated speed adjustment
option (CVI-VMA)
The CVI-VMA printed circuit replaces the standard
connection circuit and offers the additional functions
described below.
7.5.1 - Adjustment of the internal speed (VIT
INT) and maximum speed (VIT MAX) via
potentiometers
The "VIT MAX" potentiometer is used to reduce the maximum
speed for a maximum reference, independently of the setting
of K2. The "VIT INT" potentiometer is used to adjust an
operating speed : it replaces the adjustment of the external
potentiometer. Access to these settings depends on the
position of the selector switches (S1, S2, S3).
7.5.2 - Speed selection switches
The selection is made according to the following table :
Factory setting
7.6 - Electromechanical brake option
The motor must be fitted with an FCR brake adapted for the
VARMECA - 10.
The brake has an integral power supply. The brake is
energised as soon as the run command is validated. It is
released after a stop command, at the end of deceleration or
on disconnection of the power supply.
The rectifier circuit is mounted on the motor terminal plate.
7.7 - Parameter-setting console option
(CDC-VMA)
The console option provides access to the internal settings of
the controller (terminal block configuration, ramp settings,
speeds, PI, etc).
See VARMECA - 10 manual - Parameter-settings.
Description of the option :
1 CDC-VMA console
1 cable, L = 1.5m
1 single phase power supply 230V.
7.8 - Parameter-setting software option
(PEGASE VMA 10)
This option provides access to the internal settings of the
controller from a PC. The software is compatible with
WINDOWS 95-98.
See VARMECA - 10 manual - Parameter-settings.
Description of the option :
1 software pack
