Chapter 7 - Drive Parameters
FLY+BOOST
Activates both the Flying Start and Automatic Start Current
Boost.
STOP (FUNCTION)
COASTING
The ACS 300 stops supplying voltage when a Stop command is
given and the motor coasts to a stop.
DEC RAMP
Ramp deceleration as set in Page 1 / Page 4 parameter DEC 1
(or DEC 2) as selected by digital inputs in Standard and Alternate
I/O mode, refer to pages 28 to 32.
DC BRAKE
DC injection braking stops the motor by applying DC voltage to
the stator windings. By using DC braking, the motor can be
stopped in the shortest time possible, without using a dynamic
braking resistor.
DEC+BRAKE
This should be used only when a Braking Resistor ( and with
frame size R2+Braking Chopper) is connected in order to get the
best result.
DEC+HOLD
Ramp deceleration as set in Page 1 / Page 4. After ramp DC
HOLD is set on for a period defined by parameter DC BRAKE.
Parameter DC HOLD defines the intensity of the DC HOLD.
RAMP
This parameter allows you to select the shape of the
acceleration/deceleration ramp as shown in Figure 7-1. The
available options are:
LINEAR
Suitable for drives requiring steady acceleration/deceleration.
