Appendix 5. Q&A
Q1: What is BB and run on the panel?
1. BB standby state, without enabling, the motor is in the state of power failure.
2. Run running state, with enabling, the motor is in the power on state.
Q2: How to check and set the parameters?
Refer to chapter 4.6
Q3: How to change the parameters in enabled status?
P5-20=0000, enabling is invalid, P5-20=0010, enabling when power on, no need to power on again.
The default value is 0001, which means input signal from SI1, SI1 connects to low voltage, +24V
connects to high voltage (refer to chapter 3.2.2)
Q4: How to restore out of factory settings?
P5-20=0000 enabling is invalid, F0-01=1.
Q5: Which model supports bus mode?
DS3E series supports XNET communication (max 20-axis)
DS5C series supports EtherCAT communication (max 32-axis)
Q6: How to wiring for brake motor? How to modify parameters for slight slip of brake motor after
power failure?

1. P5-44 defines the terminal of the brake output signal. As shown in the figure above, the SO1 controls
brake, that is, P5-44 = 0001.
2. Extend the delay time of servo OFF P5-07 (default 500ms), and the waiting time of braking
instruction P5-09 is set to 0, which can be responded.
Q7: The initial direction is not what I want. How can I change it through a servo driver?
Change the initial direction by modifying P0-05, set the value to 0 or 1, and take effect after
re-energizing. (For mode 2, 4, 6, 7 only). If the internal speed mode (mode 3) is used, the positive and
negative values of the speed setting can be changed.
Q8: How do the two modes switch to each other?
Both P0-01 main mode and P0-02 sub-mode set the required mode. P5-30=0002 and SI2 are defined as
mode switching terminals. When the SI2 terminal has no signal, it runs according to the set mode in the
main mode P0-01. When the SI2 terminal has signal input, it runs according to the set mode in the
sub-mode P0-02.
Note: SI2 terminal signal can be switched only if it is a constant ON signal.
