APPENDIX B
DO control
When a DO terminal is set for function 20 (communication control), the host computer
can implement control on DO terminals of the drive through the communication address.
Control on DO terminals of the drive is defined as follows:
Communication Address of
Drive Running Status
Command Content
2001H
BIT0: DO1 output control
BIT1: DO2 output control
BIT2: Relay1 output control
BIT3: Relay2 output control
BIT4: FMR output control
BIT5: VDO1
BIT6: VDO2
BIT7: VDO3
BIT8: VDO4
BIT9: VDO5
Analog output AO1, AO2, high-speed pulse (FMP) output control
When AO1, AO2 and FMP are set to function 12 (Communication control), the host
computer can implement control on AO and high-speed pulse outputs by means of
communication addresses. The definition is provided in the following table.
Communication Address of AO1, AO2 and FMP Output
Command Content
AO1
2002H
0 to 7FFF indicates 0% to 100%.
AO2
2003H
FMP
2004H
Parameter initialization
This function is required when you need to perform parameter initialization on the drive
by using the host computer.
If FP-00 (User password) is set to a non-zero value, pass password verification first. The
host computer performs parameter initialization within 30s after password verification
is successful. Communication address of password verification via communication
is 1F00H. Directly write correct user password to this address to perform password
verification.
Communication address of parameter initialization by means of communication is 1F01H,
defined in the following table.
Communication Address of
Parameter Initialization
Status Definition
1F01H
1: Restore default settings
2: Clear records
4: Restore user backup parameters
501: Back up current user parameters
Communication reference
Communication set values include data set via communication such as frequency reference,
torque limit, V/F separation voltage, PID reference and PID feedback. Communication
address is 1000H. When the communication address is set in the host computer, the data
range is -10000−10000 and corresponding relative set value range is -100.00% to 100.00%.
