Actual signals and parameters 51
21 START/STOP
Start and stop modes of the motor
2102
STOP
FUNCTION
Selects the motor stop function.
COAST
COAST
Stop by cutting off the motor power supply. The motor
coasts to stop.
1
RAMP
Stop along a ramp. See parameter Group
(for more details see,
ACS355
User’s manual (3AUA0000066143 [English]).
2
22 ACCEL/DECEL
Acceleration and deceleration times.
2202
ACCELER
TIME 1
Defines the acceleration time 1, that is the time
required for the speed to change from zero to the
speed defined by parameter 2008 MAXIMUM FREQ
(in scalar control), see ACS355 User’s manual
(3AUA0000066143 [English])/
(in vector control). The control mode is
selected by parameter
.
• If speed reference increases faster than the set
acceleration rate, the motor speed follows the
acceleration rate.
• If speed reference increases slower than the set
acceleration rate, the motor speed follows the
reference signal.
• If acceleration time is set too short, the drive
automatically prolongs the acceleration, not to exceed
the drive operating limits.
The actual acceleration time depends on parameter
2204 RAMP SHAPE 1 setting (see ACS355 User’s
manual (3AUA0000066143 [English]).

ACCELER
TIME 2
Defines the acceleration time 2, that is the time
required for the speed to change from zero to the
speed defined by parameter 2008 MAXIMUM FREQ
(in scalar control), see ACS355 User’s manual
(3AUA0000066143 [English])/
(in vector control). The control mode is
selected by parameter
.
See parameter
.
Acceleration time 2 is used also as jogging
acceleration time. See parameter 1010 JOGGING
SEL in ACS355 User’s manual (3AUA0000066143
[English]).
