Dead band range of analog input 1.
Low pass filter for analog input.
Analog input voltage. Read only.
By modifying the analog offset value, the value of analog input 1 signal
becomes 0.
6.12.2 Analog input 2
Note Not all drive models have analog input 2.
When a drive has a second analog input, analog input 2 can be used as the analog current limit.
In this configuration, parameter ANIN2SCALE is used to set the current limit range in Amperes/Volts.
The following parameters are used to configure and monitor analog input 2.
Table 6-18
Define the secondary input function.
This value is the low pass filter used by the analog input. Used to filter the
high-frequency noise generated by the output or limit the signal change rate.
DC voltage offset on analog input.
Dead band range of analog input 2. Used to prevent the drive from
responding to voltage noise near the analog input zero.
Analog input voltage. Read only.
By modifying the analog offset value, the value of analog input 2 signal
becomes 0.
6.12.3 Using analog input as velocity command and current limit
Procedure: Using analog input as velocity command and current limit
Use the following program from ServoStudio2 to configure the CDHD2S. Use analog input 1
as the velocity command and analog input 2 as the current limit.
1. Define the operation mode.
Activate the Movement screen and select operation mode: Analog Velocity (OPMODE1).
When operating in "Analog velocity" mode, a signal is applied to Analog Input 1 and the drive
converts the signal into a velocity command.
2. Define velocity scaling.
Velocity Scaling is a user-defined ratio used by the drive to convert analog input into a velocity
command. In the example here, the scaling is set up to a velocity command of 100 rpm/V
