Adjustment - HNC Electric SV-E3 Series Instruction Manual

P: Position control mode, S: Speed control mode, T: Torque control mode indicates it can input signals 「○ 」 and 「 △」
in different control modes. 「 △」can switch signals according to command mode. For details, please refer to user I/O
connector CN1 terminal arrangements for each command mode.
Note 1) For I/O of locator function selection 1.

8.8 Adjustment

Table 8.8.1
Before auto tuning, perform the safety measures, such
as danger-prevention, immediate stop and impact
reducing.
In the auto tuning, the servo motor will operate at the
speed lower than the acceleration/deceleration. After
confirm it can operate safely, improve the acceleration
/deceleration gradually and adjust them.
The following occasions may not be suitable for auto tuning.
■
The inertia is too small, or too large, or the load inertia changes a lot.
●
Mechanical rigidity is too low
●
Speed is too low(300r/min or less), and acceleration/deceleration is slow.
●
Unbalance load and friction is too large, or the torque is too large or too small
●
In this case, please set the inertia ratio according to the calculated value.
The noise and vibration may occur before the estimated load characteristic settles at servo ON or control gain level changes.
■
After settling, the error may disappear. If not, perform the following measures.
Reduce the control gain level
●
Set the inertia ratio according to the calculated value in the mechanical device.
●
8.8.1 Simple tuning
Parameter description
■
①Selection of inertia condition (only for position control mode)
The characteristic of inertia condition are shown is Table 8.8.2 and Figure 8.8.1. Select it according to the device load
characteristic.
1: Applicable for the device that needs to control the heavy load, or the device that the load changes a lot, or the device of low
rigidity (emphasis on stability).
