Parameters
P2-23 Brake circuit enable 0: Disable 0 Enables the internal brake chopper.
Overload protection in software when set to
1 or 2. See rating tables for resistor sizing
guidelines.
1: lo power
2: hi power
3: Enable, no protection
P2-24 Effective switching
frequency S1, S2 230 V, 4 ... 32 kHz 16 kHz Effective power stage switching frequency.
X1: higher switching frequency means less
noise development on the motor but higher
losses at output stage.
S2 400 V, 4 ... 32 kHz 8 kHz
S3, S4 400 V, 4 ... 24 kHz 4 kHz
S5, S6 400 V, 4 ... 16 kHz 4 kHz
Auto "Auto" selects minimum possible switching
frequency for the speed range selected to
minimize losses in spindle applications.
(P2-24 must be 16 x P1-01 or greater.)
P2-25 Second deceleration ramp
time 0 s … 3000 s 0.0 s Selected automatically on mains loss if
P1-05 = 2. Can also be selected via digital
inputs during operation.
P2-26 MODBUS communication
baudrate t9.6, t19.2, t38.4, t57.6, t115.2
r9.6, r19.2, r38.4, r57.6, r115.2 0 Kbaud MODBUS RTU serial data link communica-
tion baudrate.
A ’t’ suffix indicates the drive will trip if com-
munication with the network master is lost,
after the time period set in P6-08.
An ’r’ suffix indicates that the drive will
ramp to stop if communication with the net-
work master is lost, after the time period set
in P6-08.
P2-27 Drive communication
address 0: Disable 1 Distinct drive address used for all drive
serial communications.
1 ...
63: Communication address
P2-28 Master / Slave mode select 0: Slave mode 0 When in Master mode, the drive transmits
its operational status via the serial data link.
Used to control slave drives via the serial
link. P2-27 must be 1 for Master mode.
1: Master mode
P2-29 Digital speed reference
preset scaling factor 0 … 500 %, steps of 0.1 % 100.0 % The digital speed reference input to the
drive is scaled by this factor when
P2-35 = 1. Operates on references origi-
nating from the serial data link. Can be
used as an electronic gearbox for Master /
Slave applications.
P2-30 Bipolar analog input format 0 ... 24 V
0 ... 10 V
–10 ... 10 V
–24 ... 24 V 0 ... 24 V Configures the analog input format to
match the reference signal connected to
terminal 6. Only voltage signals can be
directly connected, mA reference signals
require an external resistor connection.
P2-31 Bipolar analog input scal-
ing 0 ... 500 % 100.0 % Scales the analog input by this factor.
Set to 200 % to give full speed range con-
trol with 0 ... 5 V input
(when P2-30 = 0 ... 10 V).
P2-32 Bipolar analog input offset –500 % ... +500 % 0.0 % Sets the offset from zero at which speed
starts to ramp up.
Value is “%” of the full scale input voltage.
P2-33 2nd analog input format 0 / 24 V (digital input)
0 ... 10 V,
4..20 mA, 0 ... 20 mA 0 / 24 V Determines the format of the 2nd analog
input.Selecting 0 / 24 V sets up the input as
a digital input.
P2-34 2nd analog input scaling 0 ... 500 % 100.0 % Scales the 2nd analog input by the factor
set in this parameter.
