6 Startup and operation
6.1 Safety information and environmental conditions

Read the general safety instructions before beginning work (see Chapter 2.7 "General safety
instructions").
6.1.1 Humidity / Temperature
For continuous operation of motors, the limit values are valid according to the classification 3K4 acc.
to DIN EN 60721–3–3:1995, Table 1 (see Table "Tbl-6").
6.1.2 Environmental conditions for vibration/shock
The drive system fulfills the following specifications:
- Vibration according to DIN EN 60068–2–6:2008
- Frequency range 10 Hz –150 Hz
- Acceleration: 5 g
- Shock according to DIN EN 60068–2–27:2010
- Shock form: semi-sinusoidal
- Acceleration: 50 g
- Shock duration: 11 ms
6.2 Holding brake
The following instructions apply exclusively to electrical holding brakes.

If the motor is equipped with a holding brake, ensure that this brake is vented during startup,
and that the motor is never operated with the brake applied.

The brake is applied in a currentless state. Control of the brake is performed by the
customer using the regulating device. Technical data on the brake can be found on the
name plate and in the technical documentation.

A holding brake is no safety brake, as defined by DIN EN 13849-1 or by the German
BGHM regarding hanging axes (only available in German), and is therefore not intended to
be used as a brake for the protection of persons or as a dynamic brake.
6.2.1 Emergency stop
The effective braking torques of a holding brake differ due to physical factors, and it is necessary
to consider use during a malfunction as well as normal operation:
- In normal use, the operating principle when using the holding brake to clamp / secure an axle
in standstill is a static friction with the friction coefficient µ
H
. This means the "static holding
torque" M
4
as specified in the specification sheets is reached.
Improper use can cause damage to the motor.

Ensure that the limit values in the following sub-chapters are observed.

If this requirement cannot be fulfilled, please contact our sales
department. Always enter the serial number (SN, current designation) or
the product identification number (PIN, previous designation).

Only operate the motor when it is firmly mounted.
