Installation/Fitting
General instructions
•
Align the clamping set to the axis of the
servomotor
•
Insert the shaft(s) in the clamping set
NOTE
Do not use a hammer for fitting, since this will damage the
equipment.
•
Screw the clamping set together
Belt drives
Fit the belt pulleys for the belt drive in according with the
instructions in the original manufacturer's documentation
for the belt drive.
If using a belt drive:
•
Check the belt tension
•
The radial load on the motor shaft may not
exceed the maximum allowable radial force (see
12.8 Permitted Forces)
5.6 Electrical Installation
For the electrical connection, the relevant local and
national regulations must be observed in addition to the
information in these operating instructions.
5.6.1 Electrical Environmental Conditions
Compliance with the following electrical environmental
conditions is necessary to enable safe and effective
operation of the servomotor:
•
Earthed 3-phase mains network, 400 V AC
•
3-phase frequency 47-53 Hz
•
3-phase lines and PE line
•
Observe national statutory provisions
•
Observe leakage current
5.6.2 Connecting/Disconnecting Hybrid
Cables
WARNING
HIGH VOLTAGE
Potentially lethal voltage is present on the connectors.
Before working on the power connectors (disconnecting or
connecting the cable), disconnect the power supply
module from the mains and wait for the discharge time to
elapse.

ISD 410 Servomotor Operating Instructions
DISCHARGE TIME
The DC link capacitors of the servomotors remain charged
for some time after the mains supply is switched off at the
power supply module.
To avoid electrical shock, fully disconnect the power
supply module from the mains before carrying out
maintenance. The DC links of the individual ISD
servomotors are connected in parallel when they are
connected as a group, which increases the discharge time.
Wait for at least the time listed below before carrying out
maintenance work:
Number
1-60 servomotors
Note: High voltage may be present even if the LED on the ISD
Table 5.2 Discharge Time
General instructions for cable installation
Before installing the cable, note that:
CAUTION
Never connect or disconnect the hybrid cables to or from
the servomotors when the supply voltage is present. Doing
so will damage the electronic circuitry. Observe the
discharge time for the DC link capacitors.
NOTE
Do not forcefully connect or fit the connectors. Incorrect
connection will cause permanent damage to the
connector.

WARNING
Minimum waiting time
(discharge time)
10 minutes
connection box is not lit!
•
The female connector of the cable should be
connected to the male connector on the
servomotor
•
The male connector of the cable should be
connected to the female connector on the
servomotor
•
The feed cable is not fitted with a connector on
the input end. The cable leads are connected
directly to the terminals in the connection box
•
Sufficient slack, especially with regard to the
range of motion of the installed servomotor, must
be provided for all cables
•
All cables must be secured in accordance with
regulations and depending on conditions on site.
It must not be possible for cables to come loose,
even after prolonged operation.
