Description
Defines a safe speed reference value that is used with
supervision functions such as
• 12.3 AI supervision function
• 49.5 Communication loss action
• 50.2 FBA A comm loss func
• 50.32 FBA B comm loss func
• 58.14 Communication loss
Safe speed reference. For scaling, see parameter 46.1.
Defines the speed reference for jogging function 1. For
more information on jogging, see page 99.
Speed reference for jogging function 1. For scaling, see
parameter 46.1.
Defines the speed reference for jogging function 2. For
more information on jogging, see page 99.
Speed reference for jogging function 2. For scaling, see
parameter 46.1.
Enables/disables the critical speeds function. Also
determines whether the specified ranges are effective
in both rotating directions or not.

Each range is effective in both directions of rotation.
Defines the low limit for critical speed range 1.
Note: This value must be less than or equal to the value
of 22.53 Critical speed 1
Low limit for critical speed 1. For scaling, see parameter
46.1.
Defines the high limit for critical speed range 1.
Note: This value must be greater than or equal to the
value of 22.52 Critical speed 1
High limit for critical speed 1. For scaling, see parameter
46.1.
