Use As Directed - Kollmorgen S700 Series Safety Manual

2.2.2 Use as Directed

The servo amplifiers are components which are built into electrical equipment or
machines, and can only be used as integral components of such equipment.
If the servo amplifiers are used in residential areas, or in business or commercial
premises, then additional filter measures must be implemented by the user.
Cabinet and Wiring
The servo amplifiers may only be operated in a closed switchgear cabinet, taking into
account the ambient conditions (➜ # 54) and the dimensions (➜ # 184). Ventilation or
cooling may be necessary to prevent enclosure ambient from exceeding 40°C (104°F).
Use only copper wire. Wire size may be determined from EN 60204 (or table 310-16 of the
NEC 60°C or 75°C column for AWG size).
Power supply
Servo amplifiers in the S700 series can be supplied from 1-phase or 3-phase grounded
(earthed) industrial supply networks (TN-system, TT-system with grounded neutral point,
no more than 42kA symmetrical rated current).
S7480/S7720: In case of mains voltage asymmetry >3% a mains choke must be used.
Periodic overvoltages between outer conductor (L1, L2, L3) and housing of the servo amp-
lifier may not exceed 1000V (peak value). Transient overvoltages (< 50µs) between the
outer conductors may not exceed 1000V. Transient overvoltages (< 50µs) between outer
conductors and housing may not exceed 2000V.
For the cases of DC input power for single and group installations
S700 has not been evaluated by Kollmorgen, UL, or TÜV for replacing AC mains input with
DC input - for either single or group installations.
DC 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.
Motors
The S700 family of servo amplifiers is only intended to drive specific brushless syn-
chronous servomotors, with closed-loop control of torque, speed and/or position. The
rated voltage of the motors must be at least as high as the DC bus link voltage of the
servo amplifier.
Functional Safety
Consider the specific "use as directed" information (➜ # 58) when you use the safety
function STO.
To achieve PL e or SIL CL3, the safe switching of the pulse inhibitor must be tested peri-
odically by analyzing the feedback signal from the safety control.
Observe the user documentation for safety cards S1-2(S3) / S2-2(S4) when you use a
safety expansion card.
