Program features 77
The figure below shows typical PTC sensor resistance values as a function of the
motor operating temperature.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
For the wiring of the temperature sensor, refer to the Hardware Manual of the drive.
For encoder interface module FEN-xx connection, see the User’s Manual of the
encoder interface module.

Timers
It is possible to define four different daily or weekly time periods. The time periods can
be used to control four different timers. The on/off statuses of the four timers are
indicated by bits 0…3 of parameter 06.14 Timed func stat, from where the signal can
be connected to any parameter with a bit pointer setting (see page 93). In addition, bit
4 of parameter 06.14 is on if any one of the four timers is on.
Each time period can be assigned to multiple timers; likewise, a timer can be
controlled by multiple time periods.
