Functional Description
6.4.4

Setpoint Calculation

Setpoint setting : -10V ... +10V (REF1)
At SP.0 = 0 and 1 negative setpoint values are internally set to 0 and
the direction of rotation is adjusted digital by way of parameter SP.3
or terminals forward and reverse.
At SP.0 = 2 the direction of rotation is defined through the sign of the
setpoint.
Setpoint setting : -9999,5 rpm ... +9999,5 rpm (parameter SP .1)
At SP.0 = 3 and 4 negative setpoint values are internally set to 0 and
the direction of rotation is adjusted digital by way of parameter SP.3
or terminals forward and reverse.
At SP.0 = 5 the direction of rotation is defined through the sigh of the
setpoint.
Attention! Speed values up to +/- 9999,5 rpm can be adjusted,
however, internally the calculation is done only with the
adjusted maximum speed values.
Setpoint setting : -100%...+100% (parameter SP.2)
At SP.0 = 6 and 7 negative setpoint values are internally set to 0 and
the direction of rotation is adjusted digital by way of parameter SP.3
or terminals forward and reverse.
At SP.0 = 8 the direction of rotation is defined through the sign of the
setpoint.
