7-34
P1 - 38 ZSPD
Zero Speed Level Communication Addr.: 0126H
Default: 10 Applicable Control Mode: P/S/T
Range: 0~200
Unit: rpm
Used to set output range of zero speed signal (ZSPD).
ZSPD is activated when the drive senses the motor is equal to or below the Zero Speed Range
setting as defined in parameter P1-38.
For Example, at default ZSPD will be activated when the drive detects the motor rotating at speed
at or below 10 rpm. ZSPD will remain activated until the motor speed increases above 10 RPM.
P1 - 39 SSPD
Target Rotation Speed Communication Addr.: 0127H
Default: 3000 Applicable Control Mode: P/S/T
Range: 0~5000
Unit: rpm
When target rotation speed reaches its preset value, digital output (TSPD) is enabled. When the
forward and reverse speed of servo motor is higher than the setting value, the motor will reach
the target rotation speed, and then TSPD signal will output.
TSPD is activated once the drive has detected the motor has reached the Target Rotation Speed
setting as defined in parameter P1-39. TSPD will remain activated until the motor speed drops
below the Target Rotation Speed.
P1 - 40ϧ
VCM
Max. Analog Speed Command Communication Addr.: 0128H
Default: rated Applicable Control Mode: S
Range: 0~10000
Unit: rpm
In Speed mode, this parameter is used to set the speed at the maximum input voltage (10V) of
the analog speed command. For example, if P1-40 is set to 3000 and the input voltage is 10V, it
indicates that the speed command is 3000rpm. If P1-40 is set to 3000, but the input voltage is
changed to 5V, then the speed command is changed to 1500rpm.
Speed command = Input voltage x setting/10
Default: rated Applicable Control Mode: P/T
Range: 0~10000
Unit: rpm
In Position and Torque mode, this parameter is used to set the speed at the maximum input
voltage (10V) of the analog speed limit.
Speed limit command = Input voltage x setting/10
