Use As Directed - Kollmorgen AKD 2G-S Series Installation Manual

3.2 Use as Directed

The AKD2G drives are exclusively intended for driving suitable synchronous servomotors with closed-loop control of
torque, speed, and/or position.
AKD2G 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 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 (➜ # 33). Ventilation or
cooling may be necessary to keep the temperature within the cabinet below 40 °C or 60 °C if using extended range
operation with derating.
Only use 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, 2 or 3 phase (TN-S or TT) or DC industrial supply networks.
Drives in the AKD2G series can be supplied as follows:
AKD2G-Sxx-6Vxx:
l
1, 2 or 3 phase industrial supply networks (not more than 10 kA symmetrical rated current at 120 V and 240 V) or
DC supply.
AKD2G-Sxx-7Vxx:
l
3 phase industrial supply networks (not more than 10 kA symmetrical rated current at 240 V, 400 V and 480 V) or
DC supply.
Connection to other voltage types of supply networks is possible with an additional isolating transformer.
Repeated 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.
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 >=U /√2).

Functional Safety
l
l
Review the chapter "Use as Directed" in the Functional Safety section before using safety functionality.
The network, to which the drive is connected, must be secured according to state-of-the-
art information technology security requirements.
The user IT specialists shall analyze whether further security requirements are
applicable to ensure functional safety.
