DESCRIPTION
I2
Configurable voltage/current input using the SW2 switch.
Voltage / Current Analog Input (0~10V (max 12V) / 4~20mA
(max24mA, input resistance: 249Ω)).
TI
[1]
Frequency Setting (Pulse Train) 0~32kHz.
- Low level: 0-0.8V
- High Level: 3.5-12V
In IP66 drives, this input is shared with the P5 terminal. This
terminal must be set as TI in the parameter G5.69 to use it
as a train pulse input. For more information consult the
Programming and Software Manual.
ANALOGUE
OUTPUTS
AO
Configurable analogue output V/I (0~10V (max 12V/10mA) /
0~20 mA (max 24mA)).
TO
[1]
Pulse Output signals 0~32kHz and 0-12V. Use only a wire to
connect this signal to the input of another SD300 drive. Do
not install any resistor.
In IP66 drives, this output is shared with the Q1 terminal.
RS485
COMMUNICATION
S-
Communication port RS485 with Modbus protocol up to
115200 Kbit/s.
SG
S+
STO
SC
Safe Torque Off (STO) input available by default. Used to
block the drive’s output in an emergency. Built-in two NC
relays SA and SB. (24VDC, <25mA.)
Conditions:
- Normal Operation: Both the SA and SB terminals are
connected to the SC terminal.
- Output Block: One or both of the SA and SB terminals
lose connection with the SC terminal.
SA
SB
