Explanation of the parameters
Parameters
P7xx Control functions
All settings with regard to the fundamental control properties of the inverter are defined
within parameter group 7xx. These are all functions that the inverter executes automat-
ically when activated. They affect how the inverter responds in certain operating modes.
P70x Operating modes
P700/P701 Oper-
ating mode 1/2
This parameter is used to set the basic operating mode of the inverter for parameter sets
1 and 2. This includes in particular the definition of the motor system, encoder feedback
and corresponding control functions.
All operating modes can be set for parameter set 1. Only operating modes without en-
coder feedback can be set for parameter set 2 (see following table).
You will find detailed information on the individual operating modes in the Operating
modes chapter.
P71 x Standstill current
P710 / P711
Standstill current 1
/ 2
Setting range: 0 ... 50 % I
Mot
The standstill current is used for injecting an adjustable current into the motor when the
motor is at a standstill and the brake is applied. The standstill current can be switched
off by /CONTROLLER INHIBIT = 0. This allows the following functions to be carried out:
•
When the ambient temperature of the motor is low, it is possible to prevent the risk
of condensation and freezing (in particular of the disc brake). When you set the value
of the current, make sure that the motor cannot overheat. Recommendation: Motor
housing should be hand hot.
NOTE
When using incremental encoders (resolver, TTL, RS422, sin/cos, Hiperface
®
single-
turn), changing the parameter set invalidates the positions H510 and H511. If a valid
position is to be maintained after the parameter set has been changed, an absolute en-
coder (SSI, Hiperface
®
multi-turn) must be used.
