Chapter 6 Control Modes of Operation|ASDA-A&A+ Series
6-44 Revision April 2009
When the regenerative resistor capacity is not enough, the users can connect to multiple the same
capacity regenerative resistors in parallel to increase it.
NOTE
1) Regarding the selection of regenerative resistor, please refer to the table of regenerative resistor
specifications described in Appendix A.
6.6.4 Analog Monitor
Users can use analog monitor to observe the required analog voltage signals. ASDA-A and ASDA-A+
series servo drives provide two analog channels, they are PIN No. 15 and 16 of CN1 connector. The
parameters relative to analog monitor are shown below.
Relevant parameters:
P0 - 03 MON Analog Monitor Output Communication Addr.: 0003H
Default: 01 Related Section:
Applicable Control Mode: ALL Section 4.3.5
Unit: N/A
Range: 00 ~ 55
Settings:
not used
: CH1
B: CH2
AB: (A: CH1; B: CH2)
0: Motor speed (+/-8V / maximum motor speed)
1: Motor torque (+/-8V / maximum torque)
2: Pulse command frequency (+8Volts / 650Kpps) (ASDA-A series)
Pulse command frequency (+8Volts / 4.5Mpps) (ASDA-A+ series)
3: Speed command (+/-8Volts / maximum speed command)
4: Torque command (+/-8Volts / maximum torque command)
5: V_BUS voltage (+/-8Volts / 450V)
Note: For the setting of analog output voltage proportion, refer to the P1-04 and P1-05.
Example:
P0-03 = 01(CH1 is speed analog output)
Motor speed = (Max. motor speed × V1/8) × P1-04/100, when the output voltage value of CH1 is
V1.
