Description of terminals
Controls
Terminal 39: Common for analogue/digital outputs
Terminals 42-45: Analogue/digital outputs to display frequency,
reference, current and torque (0-20 mA or 4-20 mA
at max. 470 Ω)/statement of selected status, alarm
or warning (24 V D.C. at min. 600 Ω). See parameters
407 and 408.
Terminal 50: 10 V D.C., max. 17 mA. Supply voltage to
potentiometer and thermistor.
Terminal 53: 0- ±10 V D.C., R
i
= 10 kΩ. Analogue reference input,
voltage. See parameter 412.
Terminal 55: Common for analogue reference inputs.
Terminal 60: 0/4-20 mA, R
i
= ~188 Ω.
Analogue reference input, current.
See parameter 413.
Terminal 61: Earth connection, via switch 04, to screen for
communication cable.
See description in parameter group 5.
Terminals 68-69: RS 485 interface. Serial bus communication.
See description of parameter group 5.
Terminal 12: 24 V D.C., max. 140 mA. Supply voltage to digital
inputs (DIN0 - DIN7).
Terminals 16-33: 0/24 V, R
i
= 2 kΩ. < 5 V = logic “0”,
> 10 V = logic “1”. Digital inputs.
See p. 35 and parameters 400-406.
Terminal 20: Common for digital inputs.
Terminal 38: Earth connection to screen for control cables in units
with no terminal clamps for screen.
Terminals 01-03*): Relay output. Max. 250 V A.C., 2 A.
Min. 24 V D.C., 100 mA or 24 V a.c., 100 mA.
See parameter 409.
Terminals 04-05*): Relay output. Max. 250 V A.C., 2 A.
Min. 24 V D.C., 10 mA or 24 V A.C., 100 mA.
See parameter 410.
*) in UL versions: Max. 240 V A.C., 2 A.
NB: On using a thermistor for motor protection, it is connected between terminal 50 and terminal 16
(see description of selection in parameter 400 and outline of thermistor function, page 102).
