Use As Directed Akd-C - Kollmorgen AKD-C Series Safety Notes

AKD-C/N Safety Notes | 1 English

1.1.2 Use as Directed AKD-C

The AKD-C series power supplies are exclusively intended for operating AKD-N series
drives within a decentralized drive system.
AKD-C are components that are built into electrical plants or machines and can only be oper-
ated as integral components of these plants or machines. The manufacturer of the machine
must generate a risk assessment for the machine.
When the devices are built into machines or plant, the drive must not be used until it has been
established that the machine or plant fulfills the requirements of the regional directives.
Kollmorgen Decentral drive system
AKD-C series power supply must only be operated in a motion system with components from
Kollmorgen. Required additional Kollmorgen components are the "near servo drives" AKD-N,
hybrid cables, motor power and feedback cables, servomotors.
Assembling
AKD-C devices must only be operated in environments suitable for the ambient conditions
defined in the Installation Manual. Observe the information given in the Decentralized Sys-
tem Project Guide.
Wiring
Use only Kollmorgen CCNxN1 series of hybrid cables for connecting AKD-N and AKD-C
devices.
Power supply
AKD-C must be powered from a 3 phase industrial supply network
(not more than 42 kA symmetrical rated current at 400 V and 480 V).
For the cases of group installations and of DC powered drives
AKD has not been evaluated by Kollmorgen, UL, or TÜV for group installations nor are rat-
ings defined for DC input voltage.
Group installations must be reviewed and evaluated by the user for branch circuit protection*,
wire size, wire voltage rating, fuse protection, system dielectric requirements, overvoltage
and input** current rating.
In case of DC supplied drives the built-in EMC filter will not work. The user is responsible to
keep the conducted emissions and the immunity of the drive within the required noise levels.
* Special care must be taken in branch circuit design with mixed rating drives to avoid the
smaller drives becoming the effective 'fuse' rather than the circuit protective fuse.
** The power supply system design must ensure inrush current protection by limiting input cur-
rent during power up. DC supply polarity must be properly wired. Improper polarity of DC
power will damage the drive and void warranty.
Auxiliary voltage supply, Standby power
Standby power for the drive strings must only be used for supplying the AKD-N electronics.
24 VDC supply unit must accord to PELV (EN 60204-1) requirements.
Safe torque off
Review the section "Use as Directed" in the STO chapter in the Installation Manual before
using this safety function (SIL2, PLd, category 3 according to ISO 13849).
24 VDC supply unit for global STO supply must accord to PELV (EN 60204-1) requirements.
