State of SPD0~1: 0: indicates OFF (Normally Open); 1: indicates ON (Normally
Closed)
When SPD0 and SPD1 are both = 0 (OFF), if the control mode of operation is
Sz, then the speed command is 0. Therefore, if the users do not use analog
voltage as speed command, the users can choose Sz mode and avoid the zero
point drift problem of analog voltage signal. If the speed control mode is S mode,
then the command is the analog voltage between V-REF and GND. The setting
range of the input voltage is from -10V to +10V and the corresponding motor
speed is adjustable (Please see parameter P1-40).
When at least one of SPD0 and SPD1 is not 0 (OFF), the speed command is
internal parameter (P1-09 to P1-11). The command is valid (enabled) after
either SPD0 or SPD1 is changed.
The range of internal parameters is within -50000 ~ +50000 r/min. Setting value
= Range x Unit (0.1 r/min). For example, if P1-09 is set to +30000, the setting
value = +30000 x 0.1 r/min = +3000 r/min.
The speed command that is described in this section not only can be taken as speed
command in speed control mode (S or Sz mode) but also can be the speed limit input
command in torque control mode (T or Tz mode).
