Setup Software
The setup software is intended to be used for altering or storing the operational parameters for the digital servo
amplifiers. The servo amplifier that is connected is commissioned with the aid of the software - whereby the
drive can be directly controlled by the setup and service functions.
The characteristic nature of a PC mean that these functions are not functionally safe without further measures.
A PC-program might be unexpectedly disturbed or stopped, so that in the event of a malfunction any
movements that have already been initiated cannot be stopped from the PC.
The manufacturer of the machine must carry out a hazard analysis for the machine,
and is responsible for the functional, mechanical and personnel safety aspects of the
machine. This applies especially to the initiation of movements with the aid of
functions in the commissioning software.
Only personnel who have extensive knowledge in the fields of drive technology and
control technology are permitted to carry out online parameter setting of a drive that
is running.
Sets of data that are stored on data media are not safe from undesirable alteration
by third parties. So after you have loaded a set of data, you must check all the
parameters before enabling the servo amplifier.
Servo amplifier
The BTB/RTO contact must be wired into the safety loop of the system. The safety loop, and the Stop and
Emergency Stop functions must fulfill the requirements of EN60204, EN292 and VDI 2853.
The servo amplifiers are components which are built into electrical equipment or machines, and can only be
commissioned as integral components of such equipment.
The servo amplifier is to be used only on earthed three-phase industrial mains supply networks (TN-system,
TT-system with earthed neutral point). 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 is only admitted with an additional isolating transformer
(see installation manual page 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 servo amplifier is only intended to drive specific brushless synchronous 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-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 in the installation manual.
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 EN954-1
The -AS- restart lock must only be activated,
—
—
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.
2.
6
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).
- 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).
- 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).
