6.3 Speed mode
There are two kinds of command sources: analog input and internal register (parameters).
The Analog command controls the motor speed by scaled external voltage input. The command
register input controls the speed in two ways. The first is to set different speed values in three
command registers and then switch the speed by using DI.SPD0 and DI.SPD1 for CN1.
The second is to change the value in the register through communication. In order to deal with
the problem of non-continuous speed when switching registers, you can use the S-curve
acceleration / deceleration filter.
You need to manually set the parameters when using Manual mode, so in this mode, all auto or
auxiliary functions are disabled. In Gain adjustment mode, you can estimate the load inertia or
tune the response as well as the bandwidth. The parameter values you set at this time are
regarded as the default values.
6.3.1 Selecting the Speed command source
There are two types of Speed command sources: analog voltage and internal register
(parameters). You can select the source with DI signals for CN1. See the following table for the
command source selection:

Status of SPD0 – SPD1: 0 means that DI is off (the circuit is open); 1 means that DI is on
(the circuit is closed).
When both SPD0 and SPD1 are 0, if it is in Sz mode, the command is 0. Thus, if the
Speed command using analog voltage is not required, you can use Sz mode to address
the problem of zero drift in the voltage. If it is in S mode, the command is the voltage
difference between V-REF and GND. The range of the input voltage is between -10V and
+10V, and you can adjust the corresponding speed (P1.040).
When either one of SPD0 and SPD1 is not 0, the Speed command comes from the
internal register. The command is activated once the status of SPD0 – SPD1 is switched.
There is no need to use DI.CTRG for triggering.
