Actual signals and parameters 285
4231 TRIM SCALE Defines the multiplier for the trimming function. See section
Reference trimming on page 130.
0.0%
-100.0…100.0% Multiplier 1 = 0.1%
4232 CORRECTION
SRC
Selects the trim reference. See section Reference trimming
on page 130.
PID2REF
PID2REF PID2 reference selected by parameter 4210 (ie, signal 0129
PID 2 SETPNT value)
1
PID2OUTPUT PID2 output, ie, signal 0127 PID 2 OUTPUT value 2
4233 TRIM
SELECTION
Selects whether the trimming is used for correcting the
speed or torque reference. See section Reference trimming
on page 130.
SPEED/F
REQ
SPEED/FREQ Speed reference trimming 0
TORQUE Torque reference trimming (only for REF2 (%)) 1
43 MECH BRK
CONTROL
Control of a mechanical brake. See section Control of a
mechanical brake on page 159.
4301 BRAKE OPEN
DLY
Defines the brake open delay (= the delay between the
internal open brake command and the release of the motor
speed control). The delay counter starts when the motor
current/torque/speed has risen to the level required at brake
release (parameter 4302 BRAKE OPEN LVL or 4304
FORCED OPEN LVL) and the motor has been magnetized.
Simultaneously with the start of the counter, the brake
function energizes the relay output controlling the brake and
the brake starts opening.
0.20 s
0.00…2.50 s Delay time 1 = 0.01 s
4302 BRAKE OPEN
LVL
Defines the motor starting torque/current at brake release.
After start the drive current/torque is frozen to the set value,
until the motor is magnetized.
100%
0.0…180.0% Value as a percentage of the nominal torque T
N
(in vector
control) or the nominal current I
2N
(in scalar control).
The control mode is selected by parameter 9904 MOTOR
CTRL MODE.
1 = 0.1%
4303 BRAKE
CLOSE LVL
Defines the brake close speed. After stop the brake is
closed when drive speed falls below the set value.
4.0%
0.0…100.0% Value as a percentage of the nominal speed (in vector
control) or the nominal frequency (in scalar control). The
control mode is selected by parameter 9904 MOTOR CTRL
MODE.
1 = 0.1%
