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.

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.
