I.2
Prescribed use (Use as directed) of the servo amplifier
The servo amplifiers are components which are built into electrical equipment or machines, and can
only be used as integral components of such equipment.
The manufacturer of the machine must generate a hazard analysis for the machine, and take
appropriate measures to ensure that unforeseen movements cannot cause injury or damage to any
person or property.
The SERVOSTAR 600 family of servo amplifiers can be connected directly to symmetrically
earthed (grounded) three-phase industrial mains supply networks [TN-system, TT-system with
earthed (grounded) neutral point, not more than 5000 rms symmetrical amperes, 480VAC maxi-
mum].
The servo amplifiers must not be operated directly on power supply networks >230V without an
earth (ground) or with an asymmetrical earth (ground).
Connection to different mains supply networks (with additional isolating transformer)
ð
p.14.
Periodic overvoltages between outer conductor (L1, L2, L3) and housing of the servo amplifier 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.
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.
The SERVOSTAR 600 family of servo amplifiers is
only
intended to drive specific brushless
synchronous servomotors, with closed-loop control of torque, speed and/or position. The rated volt-
age of the motors must be at least as high as the DC-link voltage of the servo amplifier.
The servo amplifiers
may only
be operated in a closed switchgear cabinet, taking into account the
ambient conditions defined on page 17 and the dimensions shown on page 24. Ventilation or cool-
ing may be necessary to prevent enclosure ambient from exceeding 45°C (113°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).
We only guarantee the conformance of the servo amplifiers with the standards for industrial areas
(page 7), if the components (motors, cables, amplifiers etc) are delivered by Seidel.
Option -AS-, restart lock for personnel safety
The -AS- restart lock is
exclusively
intended to provide safety for personnel, by preventing the
restart of a system. To achieve this personnel safety, the wiring of the safety circuits must meet the
safety requirements of EN60204, EN292 and EN 954-1.
The -AS- restart lock must
only
be activated,
—
when the motor is no longer rotating (setpoint = 0V, speed = 0rpm, enable = 0V).
Drives with a suspended load must have an additional safe mechanical blocking
(e.g. by a motor-holding brake).
—
when the monitoring contacts (KSO1/2 and BTB/RTO) for all servo amplifiers are
wired into the control signal loop (to recognize a cable break).
The -AS- restart lock may
only
be controlled by a CNC if the control of the internal safety relay is
arranged for redundant monitoring.
The -AS- restart lock must
not
be used if the drive is to be made inactive for the following reasons :
1.
-
cleaning, maintenance and repair operations
-
long inoperative periods
In such cases, the entire system should be disconnected from the supply by the personnel,
and secured (main switch).
2.
-
emergency-stop situations
In an emergency-stop situation, the main contactor is switched off
(by the emergency-stop button or the BTB-contact in the safety circuit).
