Control Card Terminals
The drawing at the right shows the
control card terminals on the VLT
Series 3500 drive, and the
parameters that control them. A
description of the control signals and
terminals is below.
Terminal 39:
Common for analog/digital outputs.
Terminals 42 and 45:
Programmable analog or digital
outputs for indicating output
frequency, input reference, output
current and output torque. The
analog signal is 0 to 20 mA or 4 to
20 mA at a maximum of 470 W. The
digital indication can be of
operational status, or alarm or
warning. The digital signal is 24 V
DC at a minimum 600 W. See
parameters 407 and 408.
Terminal 50:
This provides the supply voltage to the potentiometer and
the thermistor. It is 10 V DC, 17 mA max.
Terminal 53:
Connect a DC analog voltage reference input to this
terminal. Voltage range is 0 to 10 V DC, R
i
= 10 kW.
See parameter 412.
Terminal 55:
Common for analog reference inputs.
Terminal 60:
Connect a DC analog current reference input to this
terminal. Current range is 0 or 4 to 20 mA, R
i
= 188 W.
See parameter 413.
Terminal 61:
Ground connection, when switch 04 is closed, this
connects to chassis ground. When switch 04 is open, an
RC filter is connected between this terminal and ground.
Terminals 68 and 69:
Serial bus communication. Parameter group 5 is used to
set up this interface.
Terminal 12:
This provides the supply voltage to digital inputs. The
voltage is 24 V DC, maximum 140 mA.
Terminals 16 and 33:
These are the digital input terminals. The input must be 0 to
24 V, R
i
= 2 kohm. < 5V = logical “0”, > 10 V = logical “1”.
See parameters 400 through 406.
Terminal 20:
Common for digital inputs.
Terminal 38:
Ground connection can be used to connect the shield on
control wires in units with no cable clamps for the shield.
Terminals 01 and 03:
Connections for Form C relay output. Maximum 240 V AC,
2 A. Minimum 24 V DC, 10 mA or 24 V AC, 100 mA. See
parameter 409.
Terminals 04 and 05:
Connections for Form A relay output. Maximum 240 V AC,
2 A. Minimum 24 V DC, 10 mA or 24 V AC, 100 mA. See
parameter 410.
NOTE:
If a thermistor is used for motor protection, it must be
wired from terminal 50 to terminal 16.
See parameter 400.
