5.3 Temperature Behaviour of the TM StepDrive under Typical Operat-
ing Conditions
i
The adjusting module temperature depends on the motor type, the motor
cable length, phase current, supply voltage and the tolerance of the compo-
nents.
In practice, it can differ from the diagrams below.
Measuring conditions or procedure:
TM StepDrive Module vertical arranged
48 V
DC
supply voltage
Motor type: ZSH 87.200.6,5
Temperatures are normalised, i.e. relatively to the ambient temperature
The power stage temperature (measured on the power stage) should not exceed 105 °C to
prevent the destruction of the hardware. The power stage has an internal emergency
shutdown
Normalised power stage temperature, max. current (3.5 A
r.m.s
),
25, 50, 75, 100 % duty cycle (ED)
