MKD Product Safety Guide | 1 English

1.2.2 Use as Directed

The MKD-C series power supplies are exclusively intended for operating MKD-N servo drive
modules within a cabinet and AKD-N decentralized servo drives.
The MKD-N family of servo drives is exclusively intended for driving suitable synchronous
servomotors with closed-loop control of torque, speed, and/or position.
MKD system modules are components that are built into electrical plants or machines and
can only be operated as integral components of these plants or machines. The manufacturer
of the machine must generate a risk assessment for the machine. The drive must not be used
until it has been established that the machine or plant fulfills the requirements of the regional
directives.
Kollmorgen multi axes drive system
MKD must only be operated in a motion system with components from Kollmorgen. Required
additional Kollmorgen components are the mains chokes, hybrid string cables, hybrid motor
cables, motor power and feedback cables, servomotors.
Assembling
MKD modules must only be operated in environments suitable for the ambient conditions
defined on (➜ # 15).
Wiring
Use only Kollmorgen cables for connecting the system components.
Power supply
MKD-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) via a mains choke 3L.
MKD-N drive modules must be powered from MKD-C intelligent power supply modules with
DC voltage from 55 VDC up to 800 VDC.
Fusing
The devices must be operated with fuse protection against power overload.
Motor voltage rating
The rated voltage of the motors must be at least as high as the DC bus link voltage divided by
√2 produced by the drive (U
For the cases of group installations and of DC powered drives
MKD-C has not been evaluated by Kollmorgen, UL, or TÜV for group installations nor are rat-
ings defined for DC input voltage.
Auxiliary voltage supply, Standby power
Standby power for the drive strings must only be used for supplying the MKD-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 (➜ # 16) before using this safety
function. 24 VDC supply unit for global STO supply must accord to PELV (EN 60204-1)
requirements.
