6.3 Switching on and operating the drive
CAUTION
The motor gets hot during operation.
Danger of burn injuries from hot surface.
Æ
Protect the surface of the motor from being touched.
Æ Let the motor cool down before touching it.
For the sequence when switching on the drive, observe any requirements or
basic conditions from the respective application.
The following sequence is one possible example, which can be used
depending on the situation or has to be adapted according to the
requirements from the application. The limit values described in Chapter 4
must be observed.
⇒ Switch on the power supply for power and logic.
⇒ Apply the digital signals for inputs A / B.
⇒ Adjust the set value input for the current limit (in the simplest case, +5
VDC for max. possible torque).
⇒ Switch on the high level at the enable input "C" to make the drive ready
for operation.
⇒ Switch on/adjust the analogue set value for the speed (motor starts)
until the desired operating point is reached.
NOTE
If the drive is plugged in or unplugged with the voltage
turned on, high voltage peaks can occur.
The integrated electronics can be damaged (drive is not "hot-
plug compatible").
Æ
Only plug in/unplug the drive system when the supply
voltage is switched on/off.
6.4 Integrated protective functions
The integrated protective functions ensure that the drive shuts off
automatically under certain operating conditions or in case of certain faults.
