AKD Safety Guide | 1 English

1.2.2 Use as Directed

The AKD drives are exclusively intended for driving suitable synchronous servomotors with
closed-loop control of torque, speed, and/or position.
AKDs 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
used with a drive must generate a risk assessment for the machine.
When the drives 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.
Cabinet and wiring
Drives must only be operated in a closed control cabinet suitable for the ambient conditions
(➜ # 13). Ventilation or cooling may be necessary to keep the temperature within the cabinet
below 40 °C.
Use only copper conductors for wiring. The conductor cross-sections can be derived from the
standard IEC 60204 (alternatively for AWG cross-sections: NEC Table 310-16, 75 °C
column).
Power supply
The drives can be supplied by 1 or 3 phase industrial supply networks.
AKD-x04807: In case of mains voltage asymmetry >3% a mains choke 3L0,24-50-2 must be
used.
Periodic overvoltages between phases (L1, L2, L3) and the housing of the drive must not
exceed 1000 V peak. In accordance with IEC 61800, voltage spikes (< 50 µs) between
phases must not exceed 1000 V. Voltage spikes (< 50 µs) between a phase and the housing
must not exceed 2000 V.
EMC filter measures for AKD-xzzz06 must be implemented by the user.
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
current during power up. DC supply polarity must be properly wired. Improper polarity of DC
power will damage the drive and void warranty.
Safe torque off
Review the section "Use as Directed" in the STO chapter (➜ # 17) before using this safety
function. Refer to the AKD Instructions Manual for more details to the STO function.
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
