Notes For North American Installations

1. EMC conformity is not usually required in North America.
In most cases, the section "Notes on EMC" can be bypassed.
In this manual, you will see references to DIN, EN and VDE
standards. These are European standards and, generally, do
not apply to North America. It is, however, the responsibility
of the user to determine which standards need to be
followed.
2. If using a DC contactor, you must connect an auxiliary
contact to a digital input of your choice and set para.
MainContAck accordingly. Set the following parameters:
20.34 Mains contactor acknowledge source =
DI6 (or any input you choose for the DC cont. auxiliary
contact)
10.24 RO1 source =
Close US style DC-Contactor 04.24b10
20.33 Mains contactor control mode = DCcontact (3)
95.37 DC voltage measurement mode = See table below
Set these parameters AFTER macros are loaded but
BEFORE the drive is commissioned.
Relay out 1 (XRO1) must be used to turn the
DC contactor on and off.
DC contactor US:
DC contactor US K1.1 is a special designed contactor with
2 x NO contacts for C1 and D1 connection and 1 x NC
contact for connection of Dynamic Brake resistor RB.
The contactor should be controlled by signal 6.24 bit 10.
The acknowledge can be connected to parameter: 20.34

3. If using Dynamic Braking, the drive allows you to select the
stopping method under three different situations.
Parameters 21.02, 21.03 and 21.04 select the stopping
method for loss of the OnOff, run command (StartStop, Jog1,
Jog2, etc.), and E-Stop input, respectively.

Each can be set to:
• Coast stop
• Ramp stop
In order to command the drive to perform a DB stop, one or
more of these parameters must be set to DynBraking. Most
users will want the drive to ramp stop when OnOff or a run
command (StartStop, Jog1, Jog2, etc.) input is cleared, and
dynamically brake when the E-Stop input is cleared. In that
case, use the following settings:
• 21.02 Off1 mode
• 21.04 Stop mode
• 21.03 Emergency stop mode =
However, any case is allowed and the final decision is left to
the user.
Other parameters control stops during faults. See:
• 31.13 Fault stop mode communication
• 31.14 Stop mode trip level 3
• 31.15 Stop mode trip level 4
If using EMF feedback with dynamic braking, set:
• 20.44 Dynamic braking delay = t
Where: t = The time (sec) it normally takes the motor to
stop during dynamic braking
External motor voltage measurement
In case field weakening is used, external DC voltage
measurement at the motor terminals is mandatory.
External DC voltage measurement for sizes H1 ... H5 can be
made using a SDCS-UCM-01 or a DC-DC transducer.
Sizes H6 ... H8 internal DC voltage measurement cables can
be rewired to the motor terminals.
