Operating Instructions
SIMOVERT MASTERDRIVES
Settings PMU and motor-operated potentiometer (P368 = 0)
This setting allows the drive to be operated via the PMU:
ON / OFF
=
/
faster / slower
=
Arrow up / down
Anticlockwise /
clockwise
=
Arrow left / right
When the
key is pressed, the motor starts and runs up to the
minimum speed set in P457.
Afterwards, the speed can be increased by pressing the
key.
The speed is decreased by pressing the
key.
The selection of setpoint sources (P368) may be restricted by the type
of factory setting (P366).

Thermal time constant of the motor
Activation of the i
2
t calculation is made by setting a parameter value >=
100 seconds.
Example: for a 1LA5063 motor, 2-pole design, the value 480 seconds
has to be set.
The thermal time constants for Siemens standard motors are given in
the following table in seconds:
