1.1.2 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 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 .
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.
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, 2 or 3 phase or DC industrial supply networks.
Drives in the AKD2G series can be supplied as follows:
AKD2G-Sxx-6Vxx:
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:
3 phase industrial supply networks (not more than 42 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.
EMC filter measures for AKD2G-Sxx-6Vxx must be implemented by the user. Refer to the
regional Accessories Manual for recommended filter types.
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
Functional Safety
Beta drives: Safety functions are neither approved nor certified yet. Do not use this func-
tionality in applications with functional safety request until further notice.
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 applic-
able to ensure functional safety.
Review the chapter "Use as Directed" in the Functional Safety section before using safety
functionality.
