Regulator Installation

Regulator Wiring Practice

• Size and install all wiring in conformance with
applicable national and all other local codes.
• Recommended
wire
terminals 1 to 26 is 1mm
2
or 0.34 mm (18 AWG or 20 AWG), for analog
signals.
• Terminal Strip Maximum Tightening Torque is
0.8 kpm or 7 in-lbs.
For signal and control wiring the
following rules should be observed,
to avoid malfunction of the drive.
• Don't route signal, control, and power wiring in
the same conduit. This may cause interference
with controller operation.
• Run cables for reference signals in separate
conduit isolated from all AC and DC power
wiring and logic control wiring.
• All reference signals should be installed with
screened cables, 2 or 3 conductor wires as
required, screen grounded at one side only
(preferable at controller housing).
• Signal or logic wires should not be run parallel
with medium voltage or electrically noisy
conductors (as the motor wires are).
• Always cross power and signal or control wires
at right angles.
Transient suppression
of contactor and relay coils:
Switching of contactor and relay coils (also
valves, fan motors e.t.c) causes transient
voltages of high frequency (bursts), which can
disturb electronic circuits.
A proved measure, to avoid potential problems,
is to provide suppression networks on all
contactor and relay coils:
- AC-coils with RC-units,
- DC-coils with diodes in non conducting
direction.
For such coils, which contacts are connected to
the drive, or which are actuated by contacts
from the drive, suppression is highly recom-
mended.

Stopping the Drive

(See WARNING note on page 1-1)
Depending on the
application, the control input at regulator
terminal 23 can be configured to provide either
a coast-to-rest or a ramp-to-rest operational
stop without disconnecting the power source
from the motor (Category 2 stop function
according to EN60204-1 Sect 9.2.2). Refer to
Regulator manual, section 4, Parameter P.025
for how to configure the operational stop.
In addition, the user can configure the drive for
operation at zero speed with power maintained
to the motor. Refer to Regulator manual,
section 4, Minimum Speed Setting Parameter
P.003

Remote Terminal Strip Digital Inputs

• Remote terminal board digital inputs are high
true (DC 24 V +10%,
Turn on voltage:
Turn off voltage:
• Inputs
no. 1-5
configurable).
• Inputs no. 6-8 are configurable by P.007 Dig.
Inputs Configuration Select
• Operation Interrupts at LOCAL, REMOTE
operation :
STOP command at local keypad is
effective in all operation modes (P.000:
LOCAL, REMOTE, etc.)
Independent Inputs
• Function Loss (dig. input no. 5) and digital
input for Ramp Selection (no. 7 or 8) are
effective independent of LOCAL/ REMOTE
selection.
• REMOTE operation:
All other digital inputs are only activated at
REMOTE operation.
