3.2 MANUAL HANDLE FEED
Overview
In the handle mode, when the manual pulse generator on the machine
operator's panel is rotated, the axis moves accordingly. Select the
axis along which the tool is to be moved with the handle feed axis
selection switches.
The minimum distance the tool is moved when the manual pulse
generator is rotated by one graduation is equal to the least input
increment.
The distance the tool is to be move can be multiplied by one of four
magnifications selected by MP1, MP2<bits 4 and 5 of G019>. The
distance can be further multiplied by 10 using parameter HNT (bit 2
of No. 7103).
The number of manual pulse generators that can be attached is as
follows.
• Controlling a manual handle:....................maximum of one
• Controlling two or three handles: .............maximum of three
(Three axes can be moved together.)
Explanation
- Manual handle feed in the jog feed mode
- Incremental feed in the manual handle feed mode
The following states can be selected using parameter JHD (bit 0 of No.
7100).

- Manual handle feed in TEACH IN JOG mode
By setting bit 1 (THD) of parameter No. 7100, manual handle feed in
TEACH IN JOG mode can be enabled or disabled.
- When manual handle feed exceeding the rapid traverse rate is specified
Parameter No. 7117 specifies as follows:
Set value 0 :
The feedrate is clamped at the rapid traverse rate and generated
pulses exceeding the rapid traverse rate are ignored.(The distance
the tool is moved may not match the graduations on the manual
pulse generator.)
