Jogging - ABB ACS850 Firmware Manual

32 Program features
• TTL Encoder Interface FEN-01: two TTL inputs, TTL output (for encoder
emulation and echo) and two digital inputs for position latching
• Absolute Encoder Interface FEN-11: absolute encoder input, TTL input, TTL
output (for encoder emulation and echo) and two digital inputs for position latching
• Resolver Interface FEN-21: resolver input, TTL input, TTL output (for encoder
emulation echo) and two digital inputs for position latching.
• HTL Encoder Interface FEN-31: HTL encoder input, TTL output (for encoder
emulation and echo) and two digital inputs for position latching.
The interface module is connected to drive option Slot 1 or 2. Note: Two encoder
interface modules of the same type are not allowed.

Jogging

Two jogging functions (1 or 2) are available. When a jogging function is activated, the
drive starts and accelerates to the defined jogging speed along the defined jogging
acceleration ramp. When the function is deactivated, the drive decelerates to a stop
along the defined jogging deceleration ramp. One push button can be used to start
and stop the drive during jogging. The jogging function is typically used during
servicing or commissioning to control the machinery locally.
Jogging functions 1 and 2 are activated by a parameter or through fieldbus. For
activation through fieldbus, see parameter
The figure and table below describe the operation of the drive during jogging. (Note
that they cannot be directly applied to jogging commands through fieldbus as those
require no enable signal; see parameter
the drive shifts to normal operation (= jogging inactive) when the drive start command
is switched on. Jog cmd = State of the jogging input; Jog enable = Jogging enabled
by the source set by parameter
command.
