120.11
Homing blocking time
Adjustable blocking period for reference run modes to the mechanical stop only.
The parameter indicates the period of time after which the mechanical stop is recognized
when the drive is blocked. The conditions for blocking are "Drive at current limit" and, at
the same time, the speed zero message.
120.12
Homing torque current limit
Limiting the torque for reference run modes to the mechanical stop only.
The limiting begins with the start of the homing to a mechanical stop and will be canceled
when the mechanical stop is recognized.
The homing modes to the mechanical adjustable stop were implemented mainly at the
SM without field weakening. The limitation of the torque is made by the limitation of the
"Max. drive current actual value"

. This means that the field current is assumed
zero so that the limit of the total current = torque current limit. When starting the homing
to the mechanical adjustable stop the total current limit is reported (

120.13
Output speed set value
Speed start value (Position Delta) of the reference run module.
120.14
Output acceleration set value
Acceleration start value of the reference run module.
120.15
Encoder angle at reference switch
Encoder angle plus adjusted offset at the reference switch in 32 Bit increments per turn.
To check whether the zero angle of the encoder is in the range of switch tolerances of the
reference switch.
NOTE!
The limit is internally determined when starting homing on the mechanical adjusted
stop. Then the value of
120.12 in ProDrive can change during homing (as the refer-
ence value
